Greetings, First, thanks for Varnish! It's a great piece of software.
Today, though, I've been pulling my hair out with a strange problem and I'm hoping someone here can help. I've got Varnish sitting in front of Apache on one server and I've got a PHP script that POSTs data from another server. If the length of the content I'm posting is over about 1500 bytes, I get an incomplete response from Varnish. Like, literally I only get half the page back. According to Wireshark, it looks like I get 1 or 2 packets of data (it's not consistent) and then there's suddently a RST/ACK. Weirder still, an almost identical request from cURL works fine. So it's either some kind of funny timing issue or it's something very specific to the way PHP makes HTTP requests. The problem disappears if: - I tell varnish to pipe instead of pass - I run the PHP script on the same server and have it POST to localhost (which makes me think timing is a factor...) - I POST less than 1kb of data I'm running varnish-2.1.3 SVN and I don't see anything unusual in the syslog or when running varnishlog (though I'm not exactly sure what I'm looking for) Here's what my request looks like: POST / HTTP/1.0 Host: web2.servicecenter.fiercemarkets.com Content-Length: 1517 XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX [...snip...] And the response I get back looks like: HTTP/1.1 403 Forbidden Server: Apache/2.2.3 (Red Hat) X-Powered-By: PHP/5.2.14 Expires: Sun, 11 Mar 1984 12:00:00 GMT Last-Modified: Thu, 30 Sep 2010 21:40:44 +0000 Cache-Control: no-cache, must-revalidate, post-check=0, pre-check=0 ETag: "1285882844" Content-Type: text/html; charset=utf-8 Content-Length: 4104 Date: Thu, 30 Sep 2010 21:40:44 GMT X-Varnish: 598880740 Age: 0 Via: 1.1 varnish Connection: close <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd";> <html xmlns="http://www.w3.org/1999/xhtml"; xml:lang="en" lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> [...snip...] The response looks fine (content-length is correct), aside from the fact that I don't get all of it. I'm stumped. Any thoughts? -- Eli Dickinson FierceMarkets, Inc. 202-824-5058 _______________________________________________ varnish-misc mailing list [email protected] http://lists.varnish-cache.org/mailman/listinfo/varnish-misc
