Hi Rob Not sure if this is the same issue (I'm new to Varnish) but http://varnish-cache.org/wiki/FAQ/Compression helped me sort out an issue I had where one browser was caching the page, but a different browser was not grabbing the cached data due to Vary: Accept-Encoding header issue.

The Issue: cachefu fails to purge cache on object changes. This means user sees stale, incorrect content. Product Versions: Plone-2.5.3, plone2.5.3, CacheFu-1.0.2, varnish-2.0.6 To reproduce: * In browser1: login and go to any page * In browser 2: view same page. * In browser 1: edit page (add some dots to title). save * In browser 2: refresh page THE BUG: browser 2 shows old version of page Another way to reproduce this is to use portal_squid tool to purge article. Same problem occurs. ./bin/varnishlog shows the error: """ 16 RxURL c http://dude.com.moneyXXX/archive/2010/february/the-thirteen-races-to-watch<http://american.aei.org/archive/2010/february/the-thirteen-races-to-watch> 16 RxProtocol c HTTP/1.0 16 VCL_call c recv 16 VCL_acl c MATCH purge localhost 16 VCL_return c lookup 16 VCL_call c hash 16 VCL_return c hash 16 VCL_call c miss 0 Debug - "VCL_error(404, Not in cache)" """ The odd thing is that normal requests from the browser produce a RxURL like: >> 13 RxURL c /archive/2010/february/the-thirteen-races-to-watch I find this odd, because the requests from the browser to varnish don't include the http host. I wonder if this version of cachefu doesn't work with varnish. A couple notes: * I tried messing with the varnish.vcl to normalize the http.host /* if (req.http.host ~ "(www.)?xxx.org") { */ /* set req.http.host = "xxx.org"; */ /* } else { */ /* error 404 req.http.host; /\* "Unknown virtual host." *\/ */ /* } */ but, it failed to produce desired results * i started messing with it because of this post: http://davidjb.com/blog/2009/01/plone-varnish-configuration-cache-hits-purge-fails and this: http://varnish-cache.org/wiki/VCLExampleNormalizingReq<http://varnish-cache.org/wiki/VCLExampleNormalizingReqUrl> Thanks for any help or guidance. -Rob _______________________________________________ varnish-misc mailing list [email protected] http://lists.varnish-cache.org/mailman/listinfo/varnish-misc
