Re: What to do when the backend sends no caching information?

Hi, If you have a look at the default VCL you'll see that varnish does a pass when the object is not cacheable (see man vcl again) or if it Sets a cookie. I think you have to override this manually, both in vcl_fetch and in vcl_recv. Per. Alecs Henry wrote: > Hi Per, > > I'm actually using the

Re: Backend response

Hi Alecs, You can modify the object in vcl_fetch. See http://varnish.projects.linpro.no/wiki/VCLExampleDefault for a flow chart of VCL. Also read through "man vcl". You can alter the headers in vcl_fetch before doing "deliver" on them which will store the object and insert it into the cache. Yes

Re: What to do when the backend sends no caching information?

Hi Per, I'm actually using the cookies in the cache (using the information provided on the website -- set req.hash += req.http.cookie;) and it works just fine! One thing that the backend does is vary on user-agent, not only content-encoding (I've removed the UA vary on the response, though). So l

Re: Backend response

Hi Per, I'm looking into changing the headers all right! Where do I do that in VCL? I wanted to try to set some cache control headers before the object was put into varnish cache. Does that even make sense? Thanks! Alecs On Fri, Dec 12, 2008 at 7:20 PM, Per Buer wrote: > Alecs Henry wrote: >

What to do when the backend sends no caching information?

Hi All, In testing varnish in different situations, I came accross a backend that sends no caching information in its responses, no Expires, cache-control or anything. Ok, I thought, I'll just set the TTL on that object (namely an html page) in VCL. Well, turns out varnish may be setting the ttl a

I wish I was a developer.. That would make my life so much easier! What about cookies? Can varnish log cookie values? Or does it fit in the same problem as the first message? Thanks! Alecs On Thu, Dec 11, 2008 at 8:34 PM, Dag-Erling Smørgrav wrote: > "Alecs Henry" writes: > > Is there any wa

Web GUI for varnish

As an early christmas gift, here is a snapshot of the web GUI being developed for the 2.1 release: http://varnish.projects.linpro.no/wiki/WebGui It is not 100% finished (saving state and security being the major issues and the code needs some cleaning), but I hope people can test and play with
