Today I found an interesting feature of my browser firefox which was no active in a nice blog : http://www.mydigitallife.info which for reference I copied here:
Hypertext Transfer Protocol or HTTP is a request/response protocol used to transfer or convey information between clients and servers. In simple words, the client makes an HTTP request and the responding server (Origin Server) which stores the resources or information will respond to it. HTTP Pipelining is a technique in which multiple requests will be send out without waiting for the corresponding responses. By customizing the HTTP Pipelining in Firefox, it helps to speed up the browsing capability. The customizing process can be done step by step as follows: -
Run your Firefox. Type in "about:config" into the address bar and press Enter. Scroll down the page and look for "network.http.pipelining", "network.http.proxy.pipelining" and "network.http.pipelining.maxrequests". You can also use the filter bar to search for these three entries.
Double click "network.http.pipelining" and "network.http.proxy.pipelining". The "False" value will automatically change to "True" Value.
Double click "network.http.pipelining.maxrequests", change the integer value in the pop-up window to 30. By entering 30, this means it will make 30 requests at once to the responding server.
Finally, just select any of the browsers and do a right-click. Select "New" followed by "Integer". There is a small pop-up box which requires you to enter the preference name. Just type in "nglayout.initialpaint.delay" and set its value to "0″ in a subsequent pop-up box. This signifies to the browser to act immediately on the information it receives without waiting for any lapse of time.
Your Firefox browser will be much faster after you have made the aforesaid.
