Re: [EMAIL PROTECTED] Adding a Header to the httpd response
Thank you Tamer for the patch. Unfortunately we can not apply this on to our production server, because of some company policies. But for sure I will check this out on our test server.

RE: [EMAIL PROTECTED] Adding a Header to the httpd response
Hi, Something like this in httpd.conf works for me: IfModule mod_headers.c LocationMatch \.(js|gif|jpe?g|css) Header append Cache-Control public /LocationMatch LocationMatch \.s?html Header append Cache-Control private /LocationMatch /IfModule so without the LocationMatch it could handle everything I think.
