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.

The problem seems to be in under compressing java files. My other software has a dhtml menu (which includes java files), and it disappears whenever i install this hack. Also the images take a while to load. Any thoughts?

try this:

edit .htaccess find
RewriteRule ^(.*)(js|css|gif|jpg)$ redir.php?file=$1$2&type=$2 [L]
coverd as
RewriteRule ^(.*)(css|gif|jpg)$ redir.php?file=$1$2&type=$2 [L]

I tried this too, definitely speeded up my site. Problem was if you hit refresh or hit f5 all CSS formatting went out of whack. Every color went white and all font went Times New Roman. Any ideas why? I have to use refresh to monitor visitors.

It's not installed now. I had it installed but removed it because it only did it when I installed MGC Chat or Cinvins RSS mods.

Did anyone watch their server loads after installing this? My loads tripled.

It may provide some speed for my end users, but I'm not going to use it at the cost of server performance.

[Jack0919]

edit .htaccess find
RewriteRule ^(.*)(js|css|gif|jpg)$ redir.php?file=$1$2&type=$2 [L]
coverd as
RewriteRule ^(.*)(js|css)$ redir.php?file=$1$2&type=$2 [L]

And test it again. I need the Number to improve the mod. thanks.

Yeah it does seem to add quite a bit of load.

Without YSlow:
1.36

With YSlow (using amended htaccess code above):
Holding at around 2.34

I was normally below 1 prior to adding the YSlow. Right now is a slow time on my server so I'm worried what will happen during a traffic surge.
