Re: HTTP optimization : advanced client caching and browser behavior

You would need a intelligent browser cache manager in between which can set the age based on the type of content or a policy set by the administrator,

Thanks

Subject: [load balancing] HTTP optimization : advanced client caching and browser behavior


Hello the ML !

I wonder what is the best practice to enforce object caching in client's browser. I usually set the Cache-control header to "max-age=xxx" seconds.

I suppose the Pragma:no-cache directive is not used by anyone now, and I know the cache-control directive overrides the "Expires" when using the max-age parameter, but between the Cache-control, Expires, Etag and Last-modified headers, is there any best practice to enforce client caching by using a header rewrite in the Load balancer ?

I personnally prefer to use Cache-control and Expires as there is no conditionnal request when a user is browsing a site to revalidate objects.

Has anyone ever played with this kind of feature ?

regards,

Surya
