Check if you send cookies, by default cookies diables caching.

Re: varnish akamai interaction
Quite a coincidence... We've moved some traffic /off/ of Akamai, but only today did we start stacking. I don't expect there to be any problems *EXCEPT* in the 304 response case -- currently Varnish strips the Expires and Cache-Control (among other) headers from 304 Not Modified responses, which could be problematic for browsers and Akamai alike. See ticket #529. Rogério Schneider wrote a patch which Tollef Fog Heen checked into trunk. A version of the patch ported to 2.0.4 is attached to that ticket, and has been stable in our production 2.0.4 environment for the last day or two. Cache and 304 behavior seems correct. However, it may depend on your Akamai config. We emit Expires, which we have Akamai use to control caching. Our default is to not cache in the absense of Expires and not touch any headers. Depending on your Akamai config, YMMV. Hope it helps, -- Ken On Jul 28, 2009, at 1:50 PM, Raymond Hall wrote: > Hi there, > > I'm wondering if anyone here has akamaized an already varinsh > accelerated website, and if so, what experiences did you get? > I'm especially interested in the Cache-Control, Expires, Last-Modified > headers interaction. > > regards, > Ray > > -- > Knowingly entering a Ponzi scheme can be rational, in the economic > sense, even at the last round of the scheme if a government will > likely bail out those participating in the Ponzi scheme.

Configuring varnish for many different domains with similar content
Hi, I'm running a network of web proxies, where the domain of each proxy is different, but any websites a user goes to will have the same content regardless of the proxy domain. For example: http://proxy1.com/visit.php?site=22abc862ce4 http://proxy2.com/visit.php?site=22abc862ce4 http://proxy3.com/visit.php?site=22abc862ce4 ... These URLs all go to the same site. However, proxy1.com, proxy2.com, etc. have different base files. Only requests that go through visit.php are the same if the site variable is the same. Is there any way I can optimize Varnish to cache the data files more effectively? Many thanks!
