mod expires and headers

[mummana]

Hi, I want to cache the static content for 7 days, I have the following settings in httpd.conf file.  The response code is always is coming as "200", the files are not caching,

 

**********************************************************************

 

# enable expirations

ExpiresActive On

 

# expire GIF images after one day

ExpiresByType image/gif "access plus 7 days"

 

# expire JPE/JPG/JPEG images after one day

ExpiresByType image/jpeg "access plus 7 days"

 

# expire CSS Files after one day

ExpiresByType text/css "access plus 7 days"

 

# expire swf Files after one day

ExpiresByType application/x-shockwave-flash "access plus 7 days"

 

# expire JavaScript after one day

ExpiresByType application/javascript "access plus 7 days"

ExpiresByType text/javascript "access plus 7 days"

 

# expire png images after one day

ExpiresByType image/png "access plus 7 days"

 

#mod_headers Caching

<FilesMatch "\.(ico|gif|jpg|jpeg|png|flv|pdf)$">

  Header append Cache-Control "public"

</FilesMatch>

 

<FilesMatch "\.(js|css|swf)$">

  Header append Cache-Control "public"

</FilesMatch>

 

**********************************************************************

 

Could you please check the above configurations and please let me know is there any problem.

 

Thanks

How do you know what code it's returning?  If you're using raw headers, then of course it's always returning a 200 code.  It's the client's responsibility to cache it.  The expires header is just a suggestion.

 

 

Those same settings work perfectly on my local Apache setup.

 

 

LoadModule expires_module modules/mod_expires.so
ExpiresActive On
ExpiresByType image/jpeg "access plus 7 days"

Hi corbin, thanks for the reply.

 

I am using Firefox/HttpFox tool to check the status codes, for any no. of requests the static content files are not cacheing, The status code always 200.

 

This is on internet and we are getting the site over proxy server.

 

Any help!!

 

Thanks

It's probably the proxy not caching.
