Hi,
We use RewriteMap extensively in Apache to look up an external service on
the header host to determine which downstream pool we want to use:
Something like this in apache:
RewriteMap d2u prg:/www/bin/dash2under.pl
RewriteRule - ${d2u:%{HOST}}
Is there a way to do this in haproxy? i.e lookup for a backend pool name
based on a header and then route the request to the backend. Please note
that we cannot simply hash the requests to any backend since specific
requests can only be handled by specific pools.
Thanks
Sachin
