NimbostratusF5 Reverse Proxy setup
Hi,
i have started using F5 newly and not comfortable with iRules yet.
Need help for a reverse proxy setup.
have 2 domain urls:
https://exampel.com/Biz/v2-xy/soapbridge/PT/*
https://exampel.com/Biz/v2/api/XY/SI.Data.RPC/SI.Data.RPC/*
these should go to one pool. And
should go to another pool.
Can some expert here help in writing a iRule to achieve this.
Hi kashif_shahzad ,
please try this :when HTTP_REQUEST { if {[HTTP::host] eq "exampel.com"}{ pool pool_1 } elseif {[HTTP::host] eq "site1.com"}{ pool pool_2 } }> Make sure with pools names within irule as it must be identical with pool name itself , usually I copy pool name and paste it within irule to make sure the names are identical.
> We can do your request by anothe approache , Do you know about Local traffic policy , it is a very useful tool in f5 and can replace iRule in many implementations but not all as irule used in more complex approaches.
> if you need me to implement your request by Local traffic policy instead of irules , I’d love to do that definitly.
I hope this helps you.

kashif_shahzadHi Mohamed,
thanks a lot for your quick response.
If we use host in the Irule it will open all the undersites from internet.
if {[HTTP::host] eq "exampel.com"}I was thinking a more specific logic to just open those url,s that come with these subdirectories in the url:
https://exampel.com/Biz/v2-xy/soapbridge/PT/*
means only url's that has host exampel.com plus /BIZ/v2-xy/soapbridge/PT/xxxxx ,
/BIZ/v2-xy/soapbridge/PT/yyyyyy and so on.
i have tried policies but was unable to get the desired results. may be i was missing something.
Hi kashif_shahzad ,
yes it simple because it forwards traffic based on host name in urls regardless what exists in the rest of requests , it is only looking for Requests hostnames

Its really simple using the Local Traffic Policy as already mentioned.
You can also make it to another virtual server.
Which is something called VIP targetting VIP, basically a layer 7 NAT.
It comes in very useful for use cases when you have only 1 IP, but need to host multiple domains/subdomains.
