Gzip Problem

[calvin199]

Hi friends,

i want to enable gzip on my site and i am having certain issues.
This topic has been covered earlier and i have read all the posts but still not getting any definite answer.

It would be kind if some of you can guide.

Host: Godaddy
Pligg version:1.0.3b
php: php 5.3



got my absolute server path using this code and also checked the absolute path from godaddy account ....
<?php
echo realpath(dirname(__FILE__));
?>

changed the gzip section in .htaccess to following changing the /home/path/to to my absolute path
php_value auto_prepend_file /home/path/to/begin_gzip.php
php_value auto_append_file /home/path/to/end_gzip.php
AddType "text/javascript" .gz
AddEncoding gzip .gz
RewriteCond %{HTTP:Accept-encoding} gzip
RewriteCond %{THE_REQUEST} ^(.*).js
RewriteCond %{SCRIPT_FILENAME}.gz -f
RewriteRule ^(.*)\.js $1.js.gz [L]


however the result is 500 internal server error... please tell me if i am missing something or i need to do in some other fashion...


Thanks for your support.

Googleing around it looks like a lot of people have problems with gzip and Godaddy.
I'm not sure there is anything that you can do besides switch hosts to one that provides more of a standardized hosting environment.

Thanks for the quick reply chuckroast.

have just sent a email to godaddy guys asking whether it is supported or not. should be getting a reply in an hour. Can you please look up this issue as i am sure many pligg owners are with godaddy and this is certainly a big issue with search engines giving greater preference to site loading times now.

If any one can throw some light on this it would be very helpful

Another update:

Just received the reply of my email to godaddy
"We do not have any restrictions that would prevent you from using GZIP with Pligg installation on your hosting account."

It would be kind for the developers to look into this issue and provide some hints as to how this thing can be accomplished.

If any one has been able to get gzip compression on their sites with godaddy kindly tell the procedure.

Any help on this issue would be great.

[calvin199]

any help coming..
Please developers kindly look this up.

I don't have a godaddy account. I'm not going to be much help.

again thanks for quick reply... just now in my desperation and hit and trial was able to get to this point..

Added this code in libs/html.php at the top:
<?php if (substr_count($_SERVER['HTTP_ACCEPT_ENCODING'], 'gzip')) ob_start("ob_gzhandler"); else ob_start(); ?>


Now using these two services :
1.whatsmyip.org/http_compression/
2.gidnetwork.com/tools/gzip-test.php

i am getting that i have successfully gzipped all my pages
however using pingdom tool i have checked with and without this code and the difference between the load time for a gzipped page and non gzipped page is almost zero.

Am i doing something wrong?
Do the changes necessarily have to be in .htaccess?
Please guide how can this thing be properly done giving a good compression and low load time.

Thanks for your time.

I use this in my .htaccess for compression and speed up loads. So far I've had very good results with it.

Another thing you can try if you are still trying to get the gzip thing to work is go though your pligg.tpl file in your template.

Near the top where there are javascript calls.. add the following to them
{if $enable_gzip_files eq 'true'}.gz{/if}

So it would look like this

filename.js
would now look like
filename.js{if $enable_gzip_files eq 'true'}.gz{/if}

Hope that helps.
