HAProxy clearly says that the error is at position 23, which looks to
be a P, but I guess this is due to the copy/paste.
A tcpdump may help understanding what type of character is at this
position.
That said, sounds weird that it works with HAProxy 1.4 and does not
anymore with 1.5-dev12.
Not really, allowed characters have changed from haproxy 1.4 to 1.5.
This is detailed in "option accept-invalid-http-request"
http://cbonte.github.com/haproxy-dconv/configuration-1.5.html#option%20accept-invalid-http-request
To complete the answer, Baptiste was right when asking to give a try to
haproxy-1.5-dev7, because the patch was applied between dev7 and dev8 :
http://haproxy.1wt.eu/git?p=haproxy.git;a=commit;h=422246eb265bc0cfebb5c872ba3d4289798f9cd3
And Willy added some documentation about that (with a note about Apache
allowing non-ascii characters) :
http://haproxy.1wt.eu/git?p=haproxy.git;a=commit;h=2f1feb99a5499510183f398730cddc2a7e7df863
So, it looks like the only alternative is to add "option
accept-invalid-http-request" in your frontend configuration.
Btw, Willy I noticed 2 weird things :
- haproxy doesn't compile anymore when DEBUG_FULL is used, I'll send the
patch in a few minutes.
- Using "-d" option on the command line gives weird results :
For the test, I call a first request with a non-ascii character, then a
valid request, then the first request again.
What we can observe is that :
- the first request gives an empty clireq line
- the valid one is OK
- then, the third (invalid) request has an non empty clireq line.
