is there a way we can use
header set last-modified "Sun Jul 18 00:32:50 EDT 2004"
with today's date directly in .htaccess file? My application is not based on php, so i can not use the trick you mentioned.

Any number of reasons. It's possible you mistakenly copied something inappropriate into the .htaccess and it's freaking out over syntax. It's also possible your server doesn't support MOD_DEFLATE or gzip.

Hi there, why do I get a 500 internal server error when I put these rules in my .htaccess?

Thanks!!

The syntax highlighter plug-in you're using has a little bug too.

It uses
display:block;
and
display:none;
in CSS file to toggle the tool bar.
But this could cause a Flash reloading in some browsers.

Chang that to
visibility: hidden;
visibility: visible
would do the trick.

Not with the rules I posted above, but it might if you have other directives going on.

Do the sequence of the htaccess directives matter?

Thanks AskApache - for anyone reading this article, check out their .htaccess rules here: http://www.askapache.com/htaccess/speed-up-your-site-with-caching-and-cache-control.html - this is one of the sites I consulted and it shows you how to set up the caching for specific files.

Cool, just make sure that you tighten up which directives apply to which files, or else your site will end up sending out all kinds of headers.. e.g., the

Header append Cache-Control "public"

would apply to every request resulting in a server response of your site.. Lock it down and you are good to go!

Hey Mark, why don't you post the .htaccess here? I don't really have a lot of time to do small jobs these days, but I don't mind taking a look.

Thanks dquinn... does it have to be at the top? Any chance you want to make a quick $50 to take a look at my htaccess and fix?

Hi Mark - MediaTemple uses mod_deflate, so you'll want to use:

SetOutputFilter DEFLATE

...instead of the gzip rules you cited, at the top of your .htaccess file.

Hey there. This is great. Im also on mediatemple with wordpress and was a bit confused regarding what htaccess rules to use. Would you mind helping me with my htaccess? Happy to donate.. Or, could you just clarify if we are supposed to use

"mod_gzip_on Yes
mod_gzip_dechunk Yes
mod_gzip_item_include file .(html?|txt|css|js|php|pl)$
mod_gzip_item_include handler ^cgi-script$
mod_gzip_item_include mime ^text/.*
mod_gzip_item_include mime ^application/x-javascript.*
mod_gzip_item_exclude mime ^image/.*
mod_gzip_item_exclude rspheader ^Content-Encoding:.*gzip.*"
