Verify whether mod_deflate in installed or not on the server. It should be installed.

$ httpd -l | grep mod_deflate

If not, install it through easyapache.

$ /scripts/easyapache

Then add the following codes in .htaccess:

 <IfModule mod_deflate.c>
     <IfModule mod_setenvif.c>
        BrowserMatch ^Mozilla/4 gzip-only-text/html
        BrowserMatch ^Mozilla/4\.0[678] no-gzip
        BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
       BrowserMatch \bMSI[E] !no-gzip !gzip-only-text/html
    </IfModule>
   <IfModule mod_headers.c>
       Header append Vary User-Agent env=!dont-vary
   </IfModule>
  <IfModule mod_filter.c>
     AddOutputFilterByType DEFLATE text/css application/x-javascript text/x-component text/html text/richtext image/svg+xml text/plain text/xsd text/xsl text/xml image/x-icon
  </IfModule>
</IfModule>

Then test it:

$ curl -A 'Mozilla/5.0 (X11; Linux i686; rv:6.0.2) Gecko/20100101 Firefox/6.0.2' -H 'Accept-Encoding: gzip, deflate' http://www.yourwebsitename.com --output filename_output

SVN: File remains in conflict

This error occurs when you didn't update the SVN and try to commit changes or, someone has made changes to this file that are conflicting with your changes. There are two ways to handle this situation. Either, you can revert back the changes you want to commit and then, update the SVN and after that make the changes again and commit. The other way is, you need to resolve the conflicted files one by one.
