Transparent Caching

the browsers should be configured explicitly to use a proxy server. this is not a headache anymore instructing each and every client to make proxy settings. Transparent caching is very handy in such cases. transparent caches are simple and they can be easily used in a network and do not require explicit coordination with other caches. Transparent caching in context of HTTP proxy caches means the transparent hijacking of the port 80, which is the default HTTP port. the cache hijacks the port 80 traffic whenever the client tries to request to the remote servers. the client does not have to configure his/her browser. instead squid transparently picks up requests and responses to the client. squid cache/proxy server acts as transparently caching servers and fulfils the clients requests of web objects, if available locally hence making efficient web browsing.
