  nginx cache varnish
  I’m trying to use Varnish to show the non-logged in users a cached version of my website. I’m able to perfectly detect if the user is logged in or out, but I can’t cache pages without extensions.There is no file extension because nginx is rewriting the URL to a php script(so caching .php does not work).For example I’d like varnish to cache: example.com example.com/forum/ example.com/contact/I have triedif (req.request == “GET” && req.url ~ “^/”) { return(lookup); } if (req.request == “GET” && req.url ~ “”) { return(lookup); } if (req.request == “GET” && req.url ~ “/”) { return(lookup); }but nothing seems to work… any help?EDIT:It still gives me X-Cache: MISS whenever I go to a extensionless page…Website is at http://www.atherys.comAnd the current VCL is…# This is a basic VCL configuration file for varnish. See the vcl(7) # man page for details on VCL syntax and semantics. # # Default backend definition.

  apache2 varnish drupal
  Recently we have configured Varnish on our server, it was successfully setup but we noticed that if we open any page in multiple browsers, the Varnish send request to Apache not matter page is cached or not. If we refresh twice on each browser it creates duplicate copies of the same page.What exactly should happen: If any page is cached by Varnish, the subsequent request should be served from Varnish itself when we are opening the same page in browser OR we are opening that page from different IP address.Following is my default.vcl filebackend default {.host = “127.0.0.1”;.port = “80”; }sub vcl_recv {if( req.url ~ “^/search/.*$”){}else {set req.url = regsub(req.url, “\?.*”, “”); }if (req.restarts == 0) {if (req.http.x-forwarded-for) {set req.http.X-Forwarded-For = req.http.X-Forwarded-For + “, ” + client.ip;} else {set req.http.X-Forwarded-For = client.ip;} }if (!req.backend.healthy) {unset req.http.Cookie; }set req.grace = 6h;if (req.url ~ “^/status\.php$” ||req.url ~ “^/update\.php$” ||req.url ~ “^/admin$” ||req.

  I would like to kindly ask someone for help. I browsed a lot of pages containing Varnish tutorials and sample VCL files, but I can’t find anything related to configurating Varnish for Magento (at least they don’t function right).All manuals I’ve found thrown a lot of errors during Varnish starting and it seems thay are suitable for old versions. (Also none of magento modules PageCache & Varnish Extension don’t work for me, because I think Varnish itself is not working right)My problem: 1.

  varnish varnish-vcl
  When sending a GET request directly to the backend with If-Modified-Since: Wed, 15 Feb 2012 07:25:00 CET set, Apache correctly returns a 304 with no content.When I send the same request through Varnish 3.0.2, it responds with a 200 and resends all the content even though the client already has it. Obviously, this isn’t a good use of bandwidth. My understanding is that Varnish supports intelligent handling of this header and should be sending a 304, so I figure I’d done something wrong with my .vcl file. Varnishlog gives this:16 SessionOpen c 84.97.17.233 64416 :8016 ReqStart c 84.97.17.233 64416 159732369016 RxRequest c GET16 RxURL c /fr/CS/CS_AU-Maboreke-6-6-2004.pdf16 RxProtocol c HTTP/1.016 RxHeader c Host: www.quotaproject.org16 RxHeader c User-Agent: Sprawk/1.3 (http://www.sprawk.com/)16 RxHeader c Accept: */*16 RxHeader c Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.716 RxHeader c Connection: close16 RxHeader c If-Modified-Since: Wed, 15 Feb 2012 07:25:00 CET16 VCL_call c recv lookup16 VCL_call c hash16 Hash c /fr/CS/CS_AU-Maboreke-6-6-2004.pdf16 Hash c www.quotaproject.org16 VCL_return c hash16 Hit c 159732275616 VCL_call c hit16 VCL_acl c NO_MATCH CTRLF516 VCL_return c deliver16 VCL_call c deliver deliver16 TxProtocol c HTTP/1.116 TxStatus c 20016 TxResponse c OK16 TxHeader c Server: Apache16 TxHeader c Last-Modified: Wed, 09 Jun 2004 16:07:50 GMT16 TxHeader c Vary: Accept-Encoding16 TxHeader c Content-Type: application/pdf16 TxHeader c Date: Wed, 22 Feb 2012 18:25:05 GMT16 TxHeader c Age: 1243216 TxHeader c Connection: close16 Gzip c U D – 107685 115763 80 796748 86141516 Length c 9830416 ReqEnd c 1597323690 1329935105.713264704 1329935106.208528996 0.000071526 0.000068426 0.49519586616 SessionClose c EOF mode16 StatSess c 84.97.17.233

  When using inline C with Varnish I’ve not been able to get /etc/varnish/default to be happy at start up.I’ve tested inline C with varnish for two things: GeoIP detection and Anti-Site-Scraping functions.The DAEMON_OPTS always complains even though I’m following what other seem to indicate works fine.My problem is that this command line start up works: varnishd -f /etc/varnish/varnish-default.conf -s file,/var/lib/varnish/varnish_storage.bin,512M -T 127.0.0.1:2000 -a 0.0.0.0:8080 -p ‘cc_command=exec cc -fpic -sha
