We have a lot of lines like that :
use_backend BACK1 if { path -i /user/path/file1.txt }
use_backend BACK2 if { path -i /user/path/file2.txt }
use_backend BACK1 if { path -i /user/path/file3.txt }
use_backend BACK1 if { path -i /user/path/file4.txt }
use_backend BACK2 if { path -i /user/path/file5.txt }
We'd like to update this very often, this is why I thought of a memcached (or
something similar) storage ...
Thanks
Thousand of ACL
Hello, I'd like to know if it's complicated to store ACL in a memcached server and live update them, or if the core of haproxy prevents to do this kind of patch. I want to add and remove lot of URI based ACL and I don't see how to do that with current options. Thanks, Neri
Re: Debugging 502 errors
Well, it seems to be a problem with Prestahop's very big headers.
I update include/common/defaults.h and set BUFSIZE 32768 instead of 16384
Seems to work.
Is it safe ?

Re: Debugging 502 errors
Hello,
Errors appears immediately, not after a long time.
I have timeout server 18, so it's not the problem ...

Debugging 502 errors
Hello,
I have a quite big problem with Prestashop under Haproxy.
When I try to use advanced features, I receive 502 errors : 502 Bad
Gateway - The server returned an invalid or incomplete response.
Error log give me something like that :
Nov 22 20:03:10 localhost haproxy[29665]: 1.2.3.4:15870
[22/Nov/2009:20:03:09.713] www srv-www1 25/0/0/-1/985 502 8396 - -
PHVN 20/19/15/9/0 0/0 {domain.tld} "POST
/boutique/urladmin/index.php?tab=AdminCatalog&id_category=1&token=bc27a5d070551ac1e057b5d54fd9dd78
HTTP/1.1"
Without Haproxy, it works fine.
I know Haproxy give 502 errors when a bad header is sent by the app
(like 'Location : index.php' instead of 'Location: index.php'), or if
the backend server unexpectedly close the connection (honestly, I
would prefer a more verbose message, who explains exactly what is the
problem).
But here, I don't see any errors like that.
Do you have some ideas in order to debug that ? More verbose logs, tests, ...
I tried with -d mode, but I can't find any 502 error ...
I use Haproxy v. 1.3.22.
Thanks in advance,
Neri
