Re: Post requests

[André Cruz]

I'm still having problems with POST requests. This time I recorded  
more information to try and make sense of this.

Version: 1.1 branch r1656
cmd line:  ./varnishd -a :8080 -b 127.0.0.1:80 -d -d -n /tmp/pretty
VCL: the default is used

The browser request as seen through wireshark:

Re: Post requests

[Poul-Henning Kamp]

Sorry for not looking at this earlier.

It was a bug that caused all requests, also piped ones, to be
rewritten to GET on the way to the backend.

Fixed in -trunk a minute ago.

 I'm having problems with POST requests. They reach varnish but nothing
 happens and the backend is not contacted.

 I see this in the log:
 11 SessionOpen  c 10.134.145.2 51721

 ...
 11 Debugc Pipe Shut read(read)
 11 Debugc Pipe Shut write(read)

 I found this ticket http://varnish.projects.linpro.no/ticket/47;
 which seemed to refer to my problem but even switching to pipe does
 not solve it.

Pipe Shut comes from the pipe code, so switching *to* pipe won't make
any difference because it already *is* pipe.

This is not an error message, BTW, just an indication that a pipe
session ended.
