Title : Interactive URL Correction for Proxy Request

0. Abstract Proxy servers are more and more important today, and they provide web page caches for users to browse quickly, and also reduce unnecessary network traffic. However, users always can't browse web pages when the URL request is not correct. Sometimes we just want to know some subjects or information about some names without the exact URL, the proxy server couldn't help us at all. Most people often use search engines to find data, but they still have to type the correct URLs of search engines. We actually need the proxy server with the ability of " Interactive URL Correction " , which means the proxy server could correct the URL request, and take the users to where they want to browse, or send back some possible URLs so that users could choose the correct URL just by one click. For example, users could just enter one word " google " , or even with some error " goggle " , and then will eventually be taken to " www.google.com ". This is very helpful for users to browse on the Internet. To accomplish the URL correction, we have applied URL preprocess and approximate URL matching technique into proxy server, so that users could just enter some important names (maybe with some errors) to browse the web pages they want. In this paper, we implement the system on the " squid " proxy system [5], and use " edit distance " as the URL error measurement. Additionally, we also list the limitation of proxy parameters and the benefits of our system.
