Any edit to .htaccess breaks Magento Site

Hi All,

This is my current .htaccess file:

RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

###########################################
## Deny access to cron.php
    <Files cron.php>

############################################
## uncomment next lines to enable cron access with base HTTP authorization
## http://httpd.apache.org/docs/2.2/howto/auth.html
##
## Warning: .htpasswd file should be placed somewhere not accessible from the web.
## This is so that folks cannot download the password file.
## For example, if your documents are served out of /usr/local/apache/htdocs
## you might want to put the password file(s) in /usr/local/apache/.

        #AuthName "Cron auth"
        #AuthUserFile ../.htpasswd
        #AuthType basic
        #Require valid-user

############################################

        Order allow,deny
        Deny from all

    </Files>

Code (markup):

I want to enable a few things such as GZip compression on my files, but everytime I add anything to my .htaccess file, might site returns a internal server error.

Here is the code I am trying to add:

## enable resulting html compression

    php_flag zlib.output_compression on

Code (markup):

Any ideas on why this keeps happening? Apparently I am just that new to all of this.

Best Wishes.

 

Not all php implementations support php_flag, how is php running on the server and what webserver is being used (sounds like the system is running PHP in cgi mode)? . Have you tried creating a .user.ini or .ini file in the desired directory?
