What does it do?
==============================
Add an Expires header

Adding an Expires header to your components with a date in the future makes them cacheable, reducing the load time of your pages. Certainly this should be done with images, but that's fairly typical. Go a step further and add it to scripts and stylesheets, too. This won't affect performance the first time users hit your page, but on subsequent page views it could reduce response times by 50% or more.

Gzip componentes

Gzipping all the js and css files types to reduce page weight. The greatest advantage is compressed to reduce the amount of data transmission network, thereby improving the client browser access speed. Of course, but also increase the burden on the server a little bit. Gzip is a more common form of HTTP compression algorithm.

Configure ETags

1. Client requests a page (A).
2. The server Back to A, and A to add a ETag.
3. Client display the page, and pages together with the ETag cache.
4. Customers once again request pages A, and the last request to the server to return to the ETag transmitted to the server.
5. Server checks the ETag, and to determine the page since the last client request has not been modified, to return to direct response to a 304 (Not Modified) and a response of the air.
So. ETag is a Tag to your components to see if they has been modified. If not here will be no request happened. Configure it is a good way.

Easy Install
==============================
1. Upload all the content to your forum directory.
2. There is no step two. It's done.

UNinstall
==============================
1. Remove all.
2. Done.

If
==============================
If the mod does not work,open and edit httpd.conf like this:
find:
#LoadModule rewrite_module modules/mod_rewrite.so
remove # as:
LoadModule rewrite_module modules/mod_rewrite.so
save, and restart apache, then it's should be OK.
-------------------------------------------------
IF there has a .htaccess File in your forum root directory yet, Do not cover it, open the .htaccess in the zip,copy all the code,add below your own .htaccess.

Very nice, however you are adding a lot of unnecessary load by constantly redirecting images through redir.php ; gziping may reduce bandwidth, but it slows the server down.

A better fix would be:

Put this in your .htaccess file:

# Turn on Expires and set default to 0 ExpiresActive On ExpiresDefault A0 # Set up caching on media files for 1 year (forever?) ExpiresDefault A29030400Header append Cache-Control "public"# Set up caching on media files for 1 weekExpiresDefault A604800Header append Cache-Control "public, proxy-revalidate"# Set up 2 Hour caching on commonly updated filesExpiresDefault A7200Header append Cache-Control "private, proxy-revalidate, must-revalidate"# Force no caching for dynamic filesExpiresDefault A0Header set Cache-Control "no-cache, no-store, must-revalidate, max-age=0, proxy-revalidate, no-transform"Header set Pragma "no-cache"

I really like where the mod designer is coming from, sadly the execution is a bit flawed.

On a small forum, this will be fine, but on a large forum the extra load it would create by gzipping everything in real time would offset the original goal of the modification, as shown by several people already.

I've personally used the htaccess rules, leaving out the modrewrite rule and redir.php.

I didn't like my goverment for a long time, I think the goverment are antagonistic to the people.

but since 2008.4.13 some media inaccurate I changed my mind. Now I try to understand my goverment and then I find how good it is.

Well,The advice you take is very important to me. I will try to find a way to balance the load and speed.

welcome to China,the Chinese is trying all the best to give you a happy and unforgettable journey.
