Hi All,

I am facing problems while setting up Apache + mod_deflate on my local application.

Below is my problem,

1] If I enable mod_deflate then I get an error in web browser as: 'The connection was reset. The connection to the server was reset while the page was loading.'

In the apache error log I get below trace,

Code:

2] If I comment the deflate settings then my application works without any issues,

Here is my deflate code,

Code:

<Location /myapp>

   <IfModule mod_deflate.c>
   
      #enable compression
 
      AddOutputFilterByType DEFLATE text/plain
      AddOutputFilterByType DEFLATE text/html
   
      #AddOutputFilterByType DEFLATE text/xml
      #AddOutputFilterByType DEFLATE text/css
      #AddOutputFilterByType DEFLATE application/xml
      #AddOutputFilterByType DEFLATE application/xhtml+xml
      #AddOutputFilterByType DEFLATE application/rss+xml
      #AddOutputFilterByType DEFLATE application/javascript
      #AddOutputFilterByType DEFLATE application/x-javascript
      
      #rules to exclude browsers that do not support compression
      BrowserMatch ^Mozilla/4 gzip-only-text/html
      BrowserMatch ^Mozilla/4\.0[678] no-gzip
      BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
      
   </IfModule>

   ExpiresActive  On
   ExpiresByType  text/plain              "access plus 10 years"
   ExpiresByType  text/css                "access plus 10 years"
   ExpiresByType  application/javascript   "access plus 10 years"
   ExpiresByType  image/gif                "access plus 10 years"
   ExpiresByType  image/jpeg               "access plus 10 years"
   ExpiresByType  image/png                "access plus 10 years"
   ExpiresByType  application/x-javascript "access plus 10 years"
   
   
</Location>


Here is my server name settings,

Code:

ServerName 127.0.0.1:80
UseCanonicalName Off


3] Also I am using websphere plugin as my web application is hosted on websphere,

Code:

WebSpherePluginConfig "C:\config\MyApache2\plugin-cfg.xml"


Could you guys please help me in making this work?

-Regards
Ajay

It seems that there is restart happening in between,


Code:


The Apache2 service is restarting.
The Apache2 service has restarted.

I have seen this caused by PHP. You should upgrade PHP to 5.2.13 or 5.3.2

Is any compression enabled in your php.ini? Twice compression can also cause such an error.

Your apache is not the newest version. Is there any reason why not to upgrade to 2.2.15 ?

I found the bug for it in bugzilla[1]. The ASF recommend to upgrade apache to 2.2 But read it yourself.
I also recommend to upgrade to 2.2.15

Agreed with the recommendation of switching to 2.2.15.
I know why they offer the download, but they should state to use 2.2.15 if it is your first install. The list of problems with 2.0.63 is ever growing and the chances of a 2.0.64 are slim if any.
