Offline Browsers - Re-defining the web experience – huh?

Diagnosis: Browsing Nightmares.


Offline Browsers (s.o.s.)

You may be extremely happy that rates of internet surfing are going rock bottom level and even at some places in India too, some ISPs such as Caltiger and Mantra Online are offering you free internet surfing over TCP/IP connections. But your happiness goes on drain when you really encounter Browsing Nightmares such as very low bandwidth, unstable connection due to less speed and unable to connect primarily due to limited bandwidth, thanks to ever increasing number of internet users. In such situations, not only your precious time gets wasted; you eventually end up in paying huge telephone bills apart from frustrations. The situations become more serious when you try to connect from remote areas, say from non-metro cities or from where there is limited access lines are provided by ISPs. Further, with a normal browser such as Internet Explorer or Netscape Navigator, when you surf the Internet and look upon a page or read the contents of the page or simply chat, then your modem becomes idle for that period of time. This idle time did not provide you any productivity and add up your Internet surfing cost for nothing. Of course, main browsers provide you off line browsing facility, but they facilitate you only the cached content of web that you had already visited on a certain day or date. Your can also set your browser to download or refresh your favorite site automatically at a preset idle time for offline browsing, but they lack features and are not intuitive. Not only TCP/IP connections, but ISDN connections and dedicated leased lines also suffer these aliments due to limited Internet Gateway Bandwidth of ISP providers. The only remedy for above situation is offline browsing using third party offline browsing tools.

Why offline browsing?

Some of the reasons that compel you to use offline browsing include:

v Convenience: You can access your downloaded, saved files any time you wish without having to connect to Internet. Frequently accessed web sites can be stored locally and updating may be synchronized with that of site. For example, if a site is updated weekly, then you need to synchronized once a week and for rest of the for whole week, you can use downloaded web site any time you wish without going online.

v Super Speed: Loading web pages from local disc becomes instantaneous and you don’t have to wait and mock upon rotating earth of IE or any other animated figures of your browser that tell you busy sign of downloading pages.

v Great Money Saver: Your overall cost of surfing will be less because of offline browsing. Some offline browsers and file down loaders try to down load many pages at a time from number of servers, thereby further reducing cost of surfing. You can further save your money by intelligent scheduling and adopting non peak load hours browsing such as Flexi Time of Satyam Online between 10 P.M. to 8 A.M. where your surfing hours are counted at discounted rates. That is, if you surf for two hours during those specific times, then you will be billed for only one hour. Besides, you don’t have to burn midnight candle for those odd hours, thanks to offline browsers. You can set your offline browser to download specific sites at those odd times, and after completion of task, it will automatically log off and even shut off your computer, ready to surf offline at later hours of your convenience. And remember, you will get blazingly high speed during those odd hours because relatively less traffic over the Internet. It means that say, a 1 MB file will take much less time to download as compared to normal traffic hours. You can also set your e-mail client such as Outlook express through task scheduler that it will connect to Internet at those odd hours, send and receive all your mail and shut down the system if you so require.

v Space Saver too: Some offline browsing tools such as WebZIP goes soft on your hard disk space, since they put downloaded internet sites in zipped format. Later you can browse those zipped files as normal Internet site with the help of either internal browser of WebZIP or any external browser such as Internet Explorer.

v Fast download: Offline browsers / File Down loaders down load several files at a time, reducing down load time. Choosing not to down load graphics or multimedia files can further reduce the down load time.

v Create firewall: Offline browsers create insulation between real dangerous worlds of Internet to your system. Illegal outside access, hacking and sneaking in to your system can be minimized if you use simple file down loader and using offline browsing.

v Other: Training web technique without involving high online cost is possible, limiting recreational surfing at commercial organization is possible, limiting access to the Quality & Quantity of web content can be effectively implemented. These are also some of major factor that advocates in favor of offline browsing.

Offline browsing is really catching, that is why you can find more than a dozen offline browsing tools packed with features and Internet file down loaders available today for your service and main browsers are also heading in this direction.

A word of caution

Using offline browsers are tricky. You have to manually evaluate an offline browser’s usability at your end. You have to tweak in to and configure an offline browser’s option and preferences manually, as the default setting are usually useless and if you use default settings, then you may end up in downloading stuff you have never wanted. For example, a file down loader may have hundreds of URL (as advertisement of those sites) in its default address to which it will attempt to refresh after its first launch. You have to manually disable or delete those unwanted URL, add your own, set depth level, define file types to download and then only it will be useful to you. Further, offline browsing may not suit every body. If you surf from site to site at random, or search for specific content and want to compare them, chat, play games over Internet etc., then there is no option other than but online browsing. If you download a full site for offline browsing, then firstly, it will not be useful for you the whole site content; secondly, it will take up lot of time and disk space.

Still, offline browsing is valuable when you visit a site regularly and frequently, a web site’s whole content attracts you, and finally, if you regularly download big files such as movies, music and program files- freeware, shareware, patches or free upgrades off the Internet.

UPDATE : Recently, a small startup company named Webaroo has started giving Offline Browsing pack for free. The highly compressed webaroo packs contains specialized, pre-downloaded contents from web that can be browsed offline. For example, its Wikipedia pack having 8 GB size in a dual layer DVD ROM will have entire contents of Wikipedia, and can be browsed through any browser without the need of an active Internet connection.
