An offline browser downloads HTML Web pages and extracts links from them. It also changes all links in a page so that they point to other files offline. Without this change, browsing Web sites offline is impossible.

Web pages may contain several areas called "frames," which are areas of a web page that contain other
web pages. Frames parsing means extracting the links to each frame`s Web page and changing them
links to point to the offline copies of these pages.

Cookies are information transferred between a web server and a
browser. They are mainly used on password-protected Web sites to
indicate that a client has been successfully authenticated. Some sites store
the username and password in cookies so that you are instantly logged on a protected Web
site when you visit it the next time.
Cookies support means that an offline browser will have no problem
downloading such password-protected Web sites, sites that use session IDs,
etc.

Almost all modern Web sites use Java scripts, which are small pieces of
programming code that make Web pages more interactive. When script code
contains links, it is necessary to detect them, load the linked pages or files
and change the links to point to offline locations.
Since there is no standard as to how links in scripts can be represented, all
offline browsers behave differently when parsing scripts. Not all links can be
successfully detected and changed. Some offline browsers can find more links than others, while some do not look for links inside scripts at all.
It is critical to provide accurate support for scripts because they are a standard part of many web sites. Failure to do so results in broken links while browsing offline and the inability to download complete Web sites on request.

Many Java scripts do not contain full links, but calculate
them from different segments. In order to find these links, it is necessary to evaluate
all script expressions. Otherwise, these links will point to missing files
offline. Offline Explorer is the only offline browser with this feature.

Java applets are separate executable files that are loaded when
you browse certain Web pages. They are used to make menus, show pictures,
animations, etc., much like Flash files.
An offline browser must be able to download Java applet files and also look inside
them to find linked files and other applets.

Flash (.SWF) files are similar to Java applets in that they are separate executable files that are
loaded when you browse certain Web pages. They are used to make menus, show
pictures, animations, etc. You must have the Flash player or plug-in installed in order to browse pages with Flash.
An offline browser must be able to download Flash files and also look inside them to find linked files,
images and other Flash files. It must also be able to change the links inside Flash to offline locations.
Some modern Flash files are compressed and only Offline Explorer can find
the links in these files.

methods of linking to other pages, images and files. Extracting and changing

All these formats are used to link to audio/video files on streaming
servers (MMS, PNM and RTSP.) They describe with special tags how to display different video, audio fragments, texts and images. Supporting these files is necessary, because most Web pages do not link directly to audio/video streams, but use the above files as redirectors.
Offline Explorer can extract links from these files, download streaming
audio/video files to your hard disk and make streaming presentations that will run
offline without an Internet connection. This allows you to view the highest
quality video files even if you have a standard modem connection.
Downloading these files will take more time than with a high-speed
connection, but you will not experience any quality drawbacks or missing
frames when viewing saved files from your hard disk.

PDF files are text files created with Adobe Acrobat software. They are widely used
because they can easily be viewed on virtually any computer device under any operating system. They are compressed to save on download time and traffic. These files often contain links to other PDF files, so without parsing and downloading these links, PDF documents may
appear to be incomplete.

Most offline browsers do not allow you to download multiple sites, but require you to open a Project,
start downloading and wait until the download completes before starting on the next site.
Some programs allow you to start different Projects at the same time, but the sites will be loaded one at a time.
Downloading video streams from different sources sometimes takes hours, so
parallel downloading is helpful. Only Offline Explorer allows you to
start downloading any number of Projects. You can start them simultaneously or consecutively (without
having to wait for the previous Project to complete.) Offline Explorer will
use all available connections to download files for each of the Projects together.

If your Projects are organized as a tree of folders and Projects, you can
select them to start a download, delete, export, etc. Selecting multiple items
at once makes it easy to perform these actions on the whole group of
Projects, instead of having to perform them separately for each Project.
Offline Explorer users benefit even more from this feature, because the
Export feature can take combine several selected Projects into a single
compressed HTML Help, MHT or ZIP file.

When you create a new Project, every offline browser assigns certain
default settings, which you can change after the fact. Most offline browsers
do not allow you to alter the default Project settings.
Project Templates are used to assign certain settings when you create a new
Project. For example, you can create a number of templates to load Web sites
with or without images, to scan a site for certain kinds of files, to
allow loading only from a certain Web site area or from several areas. These templates allow
you to quickly create similar Projects for different Web sites in just few clicks, without
having to change the settings of each Project individually.
Offline Explorer also allows you to apply a template to a group
of Projects. For example, if you need to change a setting of 20 Projects,
you can create a template with that setting, select the 20 Projects and apply
the template to them. Otherwise you would have to open the Properties dialog
of each Project separately to change the desired setting.

Scheduling allows you to set up an automatic download of Projects at a
desired time. It could be to take advantage of off-peak hours or to do an everyday download
of a certain Web site, etc. Offline Explorer Pro goes a step further by offering the URL
Macros feature, so you can schedule dynamic URLs. For example, if you want to download a page
whose URL includes the current date, URL Macros will take care of the change:
http://www.server.com/page{:month}-{:day}.htm. When Offline Explorer Pro
starts downloading this URL it converts it to http://www.server.com/page11-25.htm on November 25th.

Most Web sites use very long URLs that contain parameters, such as
file.asp?param1=value1¶m2=value2...¶mX=valueX. When an offline
browser saves such pages, it creates filenames from the URL. These filenames
can be very long. The ability to save or export to the Joliet or 8+3
filename formats helps you to prepare downloaded Web sites for CD burning or
for browsing on file systems that do not support long filenames.

Most Web sites do not store files in a single directory. When an offline
browser downloads a site, it recreates the directory and file structure.
Export, or the ability to save files to a plain directory, suppresses the creation of subdirectories. All files are stored in
the specified directory on your hard disk. If file share the same name, the program assigns them unique filenames.
For example, you may want to download a collection of images
from various Web sites and store them in one place.

This feature allows to delete downloaded Project files and Offline Explorer Enterprise will still be able
to download only new or modified files from the Web site.
The information about the files you remove is stored in a compact database and you save space by preventing
storage of duplicate files.
For example, if you downloaded a collection of large PDF files that were burned on a CD, you can
delete the files from your hard disk using the File | Delete | Only Project Files command. When you start
downloading the Project the next time, Offline Explorer Enterprise will determine if any of the deleted
files have changed and download only new and updated files.

When you update a downloaded site, you need to download only the files that have changed since the last download. This saves time and traffic. However not all Web sites and not all files support file modification checks. So, it is necessary to provide optional ways to update Web sites. Offline Explorer can check file modifications by size and CRC, and can skip checking images, because they are not changed on most Web sites.
Also, Offline Explorer can check files only up to a specified level and then simply skip checking all existing files. This works great for news sites where only the articles index page is being changed, while the article pages are not altered at all. Offline Explorer will download the index page with links to articles and then get only new pages.

Filtering URLs means specifying the links you want to download and
the links you want to skip. Keywords help you to specify a group of links by
finding only common segments.
For example, all thumbnail images on a certain site have the suffix "_tn" in the filename,
such as "photo101_tn.jpg." In this case you may exclude all files that contain
"_tn."
Offline Explorer allows you to use more complex keywords, as below:
^ad - all servers that begin with ads., such as ads.server.com,
advertisement.media.net, etc.
.net$ - all sites that are located on a .net domain.
serv*.com - server.com, www.service.com, images.server.com.au
fore[lx].com - forex.com and forel.com
images[1-5].srv.com - images1.srv.com, images2.srv.com, ... images5.srv.com
You can also use keywords like this in Offline Explorer:
http://*.srv.com/path*/[1-8]/*_tn.jpg

You can define which pages should be by searching for words in the page contents. For example, you may set an offline browser that supports this feature to save only pages that contain the word "Sport."
Offline Explorer Pro allows you to choose from a number of options when a word or phrase is found in a page.
You may be loading a site that uses sessions that expire after a certain time. In most situations an offline browser will continue loading expired Web pages that contain nothing but error message. But Offline Explorer Pro can be set to stop downloading a Project when a message is found inside the downloaded pages.

This helps you to limit some files by size. You can set a minimum and maximum file size that allowed for downloading.
For example, you may want to load only full-size images and exclude thumbnails and other small files. You can set the minimum images file size to 20 kilobytes. All images that are smaller will be skipped.

Macros are useful for scheduled automatic downloads of files with
URLs that change regularly.
For example, a weather site has an image that updates daily. Its URL
has a day number inside. Thus, http://www.weather.com/image5.png
corresponds to the 5th day of the current month, while
http://www.weather.com/image12.png corresponds to the 12th day of the current month.
In this case, the following URL macro is useful:
http://www.weather.com/image{:day}.png
When Offline Explorer starts downloading the Project, it substitutes macros
with their values. Macro should start with the {: symbol and end with the } symbol.
Macros also allow you to download sequences of URLs. For example:
http://www.weather.com/image{:1..100}.png
This results in the following URLs download:
http://www.weather.com/image1.png
http://www.weather.com/image2.png
...
http://www.weather.com/image99.png
http://www.weather.com/image100.png

An offline browser should be able to change the number of files it loads simultaneously. A lower number of connections is good for servers that cannot handle many requests, blocking your IP address if you overload them. On high-speed servers, increasing the number of connections will increase downloading speed.

There are lots of audio and video streams available, but you can`t save them to your disk within your browser, Media Player or Real Player. Offline Explorer Pro can do this for you. Simply give it RTSP://, PNM:// or MMS:// URL and watch the file from your hard disk. You can also download the file with the highest possible quality even on a slow modem Internet connection. Enjoying downloaded files offline is much better, because you will never experience delays, stalled video, etc.
