Nimbostratus
Nimbostratusredirect to two pools with diff ports
I'm pretty new to irule. I'm trying to access two different web instances using URIs. Requirement is to use single VIP. e.g.,
http://www.mycompany.com/ ;goes to pool1:port1
http://www.mycompany.com/app2 ;goes to pool2:port2 with no app2 in url
Both web instances are on same server(s) listening on two different TCP ports and have their own index.html. I have created pool1 and pool2 with following irule:
when HTTP_REQUEST {
if [string tolower [HTTP::path]] eq "/app2"}{
pool Pool_2
}else {
pool Pool_1
}
}
The problem is that I can only get to pool2 by using a file called "app2" in the 2nd web instance folder and "app2" word is visible. I have also tried: HTTP::redirect "http://[HTTP::host]/" after pool pool_2 but that goes to pool1.
How do I get F5 to send it to /index.html for second web instance for http://www.mycompany.com/app2 request and remove "app2" from the URL?
Any help is appreciated very much. Thanks.
- The_BhattmanHi AFara2000,
You could change the URI in the following mannerwhen HTTP_REQUEST { switch [string tolower [HTTP::uri]] { "/app2" { HTTP::uri /[HTTP::uri] pool Pool_2 } default { pool Pool_1 } } }
I used the switch command because in the long run it executes faster then IF-ELSE.
I hope this helps

afara2000_1973Thanks Bhattman for your code but that didn't take care of /app2 in uri. I decided to use /app2/* for all web application 2 paths. Therefore, I modified your code and this seems to be working fine:
when HTTP_REQUEST {
-glob: allow string pattern matching to check within requested path
switch -glob [string tolower [HTTP::path]] {
"/app2" {
log local0. "Exact macth for /app2 - sending to pool_2 in [HTTP::uri]"
HTTP::uri [HTTP::uri]/
pool Pool_2
}
"/app2/*" {
log local0. "Matched /app2/* - No rewrite, sending to pool_2 for [HTTP::uri]"
pool Pool_2
}
default {
log local0. "No match for app2, sending to default pool_1 for [HTTP::uri]"
pool Pool_1
}
}
}
My next step is to expand this code to use https instead of http. Can this code still be used? I will be planning to terminate SSL using clientside and serverside SSL certs. Any hint or help would be highly appreciated. Thanks,
Al
