iRules not working

[BK1]

Hi,

I have set-up one F5 node in lab environment. Everything is working fine except iRules. Some of the iRules are not working, syntax is correct. I tried everything but it is not working. Need ur help. Simple redirect using if statement is not happening. e.g. below one.

F5's is running on 14.1.

if {[HTTP::host] equals "abc.com" }

{HTTP:: redirect "par.com"}

Need your help.

Hello BK,

This is may be happening because there're some changes in iRules syntax/behavior for respond and redirect in 14.1 and 15.x version.

Below article will help you.

Oh I see! Thanks for letting me know. I was not aware of this change in behaviour. I will try changes suggested in the article. But​ it's seems to be only workaround but not fix. 😞

As of now, this is the only solution.

with the workaround given in the article, iRules are working now. I tried multiple iRules. Thank you.​

v14 and v15 use policy

if you want irule, try this one

when HTTP_REQUEST {

 switch [HTTP::host] {

"abc.com" {

HTTP::respond 301 Location "https://par.com[HTTP::uri]" 

}

}

}

👌
