Hi!

I've been running pound to do simple load balancing/failover between 3
machines using round robin and session tracking via cookies. Now I have new
need. I need to be able to send an additional request parameter (ie
myPage.php?host=host_1) and have pound direct me to host_1 instead of the
one in the session (or instead of the next one in the case of no cookie).

Is that possible using pound?

Psedo code:
if host_parameter
  use host_parameter
else if session cookie
  use session cookie
else
  use default / round robin

Thanks

Yes, we do something similar here.  Create a new "Service" directives, 
using "URL" directive to catch "host=host_1". It'll look something like 
this:
Service
    URL ".*host=host_1*"
    BackEnd
       Address host_1
       Port   80
    End
End

Make sure this Service is declared before your session cookie and 
round-robin Service directives.

I've been playing around with a similar configuration here and it seems
to work the way I want it to.

Basically, I set up a bunch of different services that match on
different extensions.

I believe the first match in the config is what gets used.

So, if you have a service (listed first) that looks for the host
parameter it should trigger that service first.  I believe this is how
it works, at least it seems to behave that way.  Can anyone confirm that
the first match is what gets used?

Thanks.

Yes, in my experience that's how pound works.

Thanks. This looks promising, I have one question and one problem though :)

1) What did I do to deserv "pound: MONITOR: worker exited normally 127,
restarting..." on all request? I don't seem to get anything back either, it
just closes immediately.

2) Will the services that holds the URL requirement store information about
the cookies for future request? I would like it to go the same machine on
subsequent calls even without the host=host_1.

Thanks.

Is there any other source of help than this mailinglist?

Thanks.

I've never heard of this issue, but you could always look through the source to
determine the exact conditions need to print such a message.  That might be the
next place to consider...

I compiled the newest one and it works. Thanks. That should teach me to not
use old packages :)

Is there any way to do it? Like adding the same session block to all
services?

Thanks.
