vb.org Archive - mod deflate, gzip compression and login

Hello,
I was looking for a gzip compression on the forum (to make it fastly) and on my webserver was activated the mod deflate. After this, the hoster suggested to put theese instruction to the .htaccess file:

PHP Code:


		
			
<IfModule mod_deflate.c>

AddOutputFilterByType DEFLATE text/plain text/html text/css text/javascript application/javascript application/x-javascript

</IfModule>

<IfModule mod_expires.c>

ExpiresActive On

ExpiresByType text/html "access plus 1 day" 

ExpiresByType text/css "access plus 1 month"

ExpiresByType text/plain "access plus 1 day"

ExpiresByType text/javascript "access plus 1 day"

ExpiresByType image/gif "access plus 1 month"

ExpiresByType image/png "access plus 1 month"

ExpiresByType image/jpeg "access plus 1 month"

ExpiresByType application/javascript "access plus 1 week"

ExpiresByType application/x-javascript "access plus 1 week"

</IfModule>

After, users have login problem: they try to log in unsuccesfully. Removing theese line, works fine.
Do you think there is something wrong in the instructions or the compression causes problems to the board?

Thank you
