this topic really is interesting, i went a looking for the .httacess codes todo this as pete suggested and man did i get some cool answers im not all that confident in adding anything that i dont understand completely what it's doing. im not using a test site at all so it would be going right on a live site, 2 posts that stood out where:
forums.hostgator.com/speed-up-your-site-htaccess-t132870.html
and
seomoz.org/blog/15-tips-to-speed-up-your-website
the seomoz one look's more like what im after, would anyone be able to confirm this would work with oxwall
this code below in particular, id test it but id have to set oxwall up on another domain and install all the plugins blah blah , and i know a bunch you guys got 3 demo sites already. many thanks in advance.
