php----deflate and .htaccess

What does these code mean? It is from the .htaccess file.

<IfModule mod_deflate.c>
SetOutputFilter DEFLATE
 </IfModule>

RewriteEngine on
RewriteRule ^([^./]{3}[^.]*)$ /index.php?page=$1 [QSA,L]

Can someone explain the last line? thank you

I think you wanted to know about the rewrite rule?

^ start the expressoin

^. any character

/ then slash

{3} means match previous item 3 times

^. means match any character

* means match zero or more of the preceeding expression

$ end the expression

QSA appends the variables passed to the end L means last rule

So match any character and then a slash (three times) and then any characters after it...

So 

/a/b/c/myfile.txt

would be rewriten to

/index.php?page=/a/b/c/myfile.txt

and (for example from a login form post)

/a/b/c/myfile.php?username=myname&password=mypassword

would be rewritten to

/index.php?page=/a/b/c/myfile.txt&username=myname&password=mypassword

TheSetOutputFilter DEFLATE compresses traffic sent from the webserver to decrease response time and make the website faster.

The Rewrite Rule uses a regular expression to match a specific pattern in your URL and modify it so that something else happens.

  RewriteRule ^([^./]{3}[^.]*)$ /index.php?page=$1 [QSA,L] //expect someone can explain

Here is a resource on URL Rewriting: http://httpd.apache.org/docs/2.0/misc/rewriteguide.html

The mod_deflate module provides the DEFLATE output filter that allows output from your server to be compressed before being sent to the client over the network.

http://httpd.apache.org/docs/2.2/mod/mod_deflate.html

Basically it compresses data sent by apache to then be uncompressed by the browser, reducing the payload sent between server and browser

This:

<IfModule mod_deflate.c>
  SetOutputFilter DEFLATE
   </IfModule>

means: The output sent to the client will be compressed. See http://httpd.apache.org/docs/2.0/mod/mod_deflate.html
