.htaccess speed up site

Increase your page load times and save bandwidth with easy and really effective methods using apache htaccess directives. This module controls the setting of the Expires HTTP header and the max-age directive of the Cache-Control HTTP header in server responses. The expiration date can set to be relative to either the time the source file was last modified, or to the time of the client access.
These HTTP headers are an instruction to the client about the document’s validity and persistence. If cached, the document may be fetched from the cache rather than from the source until this time has passed. After that, the cache copy is considered expired and invalid, and a new copy must be obtained from the source.
