url redirect irule

i tried using the below irule no luck so trying to understand where my logic is failing. If i can get the working irule that would be great

when HTTP_REQUEST {

 if { [class match [string tolower [HTTP::host]] contains *.host1.abc.com ] } {

          { HTTP::redirect " *.host2.xyz.com" /[HTTP::uri]

       #log local0. "Client [IP::client_addr]:[TCP::client_port] -> [HTTP::host][HTTP::uri]" }

 }

}

Hi Sam10,

Can you try this?

when HTTP_REQUEST {
    if { [string tolower [HTTP::host]] contains "host1.abc.com" } {
		set host [string map -nocase {"host1.abc.com" "host2.xyz.com"} [HTTP::host]]
		HTTP::redirect "http://$host[HTTP::uri]"
	}
}

No luck , still running into the issue , page cannot be displayed.

I see the response going to the backend server , but server never responding back. I see a syn from F5 ,after 3 TCP retransmission from F5 , no response from the server . F5 is closing the connection .

This is the request i see in wireshark from client to F5.

   GET / HTTP/1.1

Host: tools.host1.abc.com

User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:78.0) Gecko/20100101 Firefox/78.0

Accept-Language: en-US,en;q=0.5

Accept-Encoding: gzip, deflate, br

Upgrade-Insecure-Requests: 1

But no response from the backend the server.

and also need HTTPs url redirect,

thankyou , finally got this working as expected.

1. when HTTP_REQUEST {
2. if { [string tolower [HTTP::host]] contains "host1.abc.com" } {
3. set host [string map -nocase {"host1.abc.com" "host2.xyz.com"} [HTTP::host]]
4. HTTP::redirect "http://$host[HTTP::uri]"
5. }
6. }
