I agree with what you said. But only computers in local network can use Proxy sever. However,if we are not in a local network,instead the Internet,it cannt work.The background of what I described is in the Internet,which we can regard it as a P2P network that consists of countless autonomous peers.So maybe a plug-in into the browsers can be developed to work out it ?What you descibe is already possible. However, it\'s not a browser feature, but a network one. It\'s known as a Proxy server. That\'s a machine on your local network which saves the last few MBs (how much exactly is set by the network administrator) and if another person inside that network downloads this page, he/she would download from the Proxy instead.There are however few drawbacks of all this. For starters, you can\'t disable the Proxy\'s cache. Because of this, popular pages are practically not going to be updated before they are out of the proxy\'s cache and for that they must become less popular. You must also specifically tell your every application which uses internet connection that you have a Proxy server. If you don\'t set it correct or don\'t set it at all, there won\'t be any connection.That\'s infact the reason why most of the times, network admins give the proxy a really small cache and therefore you almost never feel speed boost. Because of all of the above, Proxy servers are not something for everyone. It\'s infact a really annoying technology most of the times. -
Hi guys! At present, we know when we log on to one website to browse information(e.g. News),our computer will build a connection to the website server for downloading the data of the web page. Sometimes we may find it very slow to open a web page since the network is busy. Considering the recently popular P2P technogy, if some computers near us have read the web pages of the website,which means that some data have been saved in these computers` buffers,then we can connect to them for downloading these data,instead of directly connecting to the website. The advantage is to release the load of the website server,and more importantly is to improve the speed of browsering web pages. I am not sure about whether some browsers have implemented the function I just said or the like before.Does somebody know this? Or I`d like to see you guys comments on my thinking. Is my thingking feasible? Thanks!

hi guys! I just learn XQuery these days. But now,i wonder the way to see the result of XQuery statement applied to specific XML doc. Or is there some tool, just like SQL server 2000 where we can get the result when we use some SQL script to operate the databases?

I am very interested in W3School tutorials,especially the subjects related to XML.I really appreciate W3School because i`ve learned a lot from them. But now i have a problem,that is i could not log on to Internet very often so that it is not very convenient for me to learn these useful materials. So i am wondering whether i can download these tutorials ? can anyone tell me ? thank you!
