irule to pick a number out of a URI and make it the port

Steve,

 

Thanks for your help!

 

If I get behind the firewall and F5 I can go to

 

http://172.20.5.15:8080/ESB/App1/

 

I have my pool set for 8080 and 172.20.5.15 is the only host in my pool.

It looks like it works with 5 but it isn't doing the port, it is only working for the default pool. So I think it is picking up the right URI and just going to the default pool which is 8080. Not working in the App2 and App3 because of the port? I don't have to define the pools in the rule do I? Can the rule push traffic to a pool that isn't in the config for the Vhost?

 

 

Thanks

 

Joe

 

 

 

 

Hmmm, I think I'm missing something here. Can you try this - just an extra log statement to record the original URI etc.

when HTTP_REQUEST {
 set newuri [findstr [HTTP::uri] "/" "4"]
 log local0. "Original request is: [HTTP::host][HTTP::uri]"
 log local0. "New URI is: $newuri"
 set newport [findstr [HTTP::uri] "/" "0" "/"]
 HTTP::uri "$newuri"
 log local0. "New Port is: $newport"
 HTTP::header replace Host "[HTTP::host]:$newport"

 if { $newport ne "" } {
  Use the relevant Pool
  pool pool_$newport }
 else {
  log local0. "Newport Variable was empty"
 }
}

Steve, I had to change your code to be 5 as that seems to work but here is the messages I get

It is not populating the port value that is where I am stumped? The only reason the 8080 works is because that is the default pool.

 

Thanks

 

Joe

 

Odd. OK, how about this (I've removed some double quotes and used a length rather than / for the terminator with the second findstr command);

when HTTP_REQUEST {
 set newuri [findstr [HTTP::uri] "/" 5]
 log local0. "Original request is: [HTTP::host][HTTP::uri]"
 log local0. "New URI is: $newuri"
 set newport [findstr [HTTP::uri] "/" 0 4]
 HTTP::uri "$newuri"
 log local0. "New Port is: $newport"
 HTTP::header replace Host "[HTTP::host]:$newport"

 if { $newport ne "" } {
  Use the relevant Pool
  pool pool_$newport }
 else {
  log local0. "Newport Variable was empty"
 }
}

OH MAN, we are so close!!!

 

I was getting /808 so I changed set newport [findstr [HTTP::uri] "/" 0 4] to set newport [findstr [HTTP::uri] "/" 0 5] and am now getting the port but need to lose the /

 

how would I do that?

Sweet. I think we can just change this;

[findstr [HTTP::uri] "/" 1 5]

This might be better (if it works);

[findstr [HTTP::uri] "/" 0 4]

Steve, you SO ROCK!!! Thank you so much for your help!

 

I had to change the 5 back to a 4 once I added the 1. It also works with or without the / in "" I will investigate that more.

 

the only strange thing I am seeing now is this line

 

Tue Apr 23 15:58:24 EDT 2013 info tmm tmm[8659] Rule /Common/log-test : chucktest.test.com:8082:8082

 

not sure why the port is showing up twice or if it matters? It works and that is what REALLY matters!!!!

 

 

Here is the final code if anyone wants to use it

 

 

when HTTP_REQUEST {

 

set newuri [findstr [HTTP::uri] "/" 5]

 

log local0. "Original request is: [HTTP::host][HTTP::uri]"

 

log local0. "New URI is: $newuri"

 

set newport [findstr [HTTP::uri] "/" 1 4]

 

HTTP::uri "$newuri"

 

log local0. "New Port is: $newport"

 

HTTP::header replace Host "[HTTP::host]:$newport"

 

 

if { $newport ne "" } {

 

Use the relevant Pool

 

pool chuckpool_$newport }

 

else {

 

log local0. "Newport Variable was empty"

 

}

 

}

 

 

I set this up with pools named chuckpool_8080, chuckpool_8081... and then I tell the developers to just use the port they want in the URI as in newapp.test.com/8080/app/and/more/crap the script pulls out the port and sends it to the pool chuckpool_8080 (or whatever they choose) and I just use one of the pools as the default. It puts the URI back on and you get to the pool you want with the URI intact.

 

 

Thank you again SO MUCH!

 

Joe

 

Glad we finally got there, thanks.
