Hi folks, newbie and tasked to remove the tcp port from a redirect’s Location header. Without a test system I cannot check it and would appreciate any feedback before going live. Would this iRule work?

when HTTP\_RESPONSE {

if { [HTTP::is\_redirect] } {

[string map [list :52600 “”] [HTTP::header Location]]

}

}

Try:

when HTTP\_RESPONSE {

if { [HTTP::is\_redirect] } {

HTTP::header replace Location [getfield [HTTP::header value Location] : 1]

}

}

Two problems:

1. if the Location contains an absolute path like “[https://somehost:52600](https://somehost:52600)”, then this iRule would redirect me to “https” with nothing behind it, correct?

2. if the Location contains an URI behind the host like “somehost:52600/somepath/somefile”, then the iRule would redirect me to “somehost” without any path, correct?

You are right. Apologies for not considering that.

when HTTP\_RESPONSE {

if { [HTTP::is\_redirect] } {

regsub -all “:52600” [HTTP::header Location] “” newlocation

HTTP::header replace Location $newlocation

}

}

You could use string commands for this as well. Here are a few options which should be a bit more efficient than regsub:
