Currently, i am caching gif images and css files. Only problem i see is that each time when i load my website it saves css file again the cache with new expiry date, that means it is not loading it from cache
Initially i went to my home page and saw temporary internet file that said expiry date of my css is 1/3/2007 2:04 PM. After five minutes i refreshed my page again and the expiry date of my css was 1/3/2007 2:09 PM
Please advice how can change my headers in htaccess so that each time the site opens it check if my css file is modified or not..If it was modified before the expiry then update the css file in cache otherwise just use the one in the cache
Basically this is what i want
i have a dyamic page but css and js script file hardly change. So what i exactly want is the header code, that checks for those css and js file, if they have been modified since last access time...
If modified then copy the new file from the cache otherwise use it from the cache
