IRULE to redirect traffic from URL to another URL except for specific URI

HI Everyone,

 

I am looking for an irule where any traffic from host abc.com should redirect to bbc.com expect when it has URI of /XYZ on host abc.com.

 

I tried below irule but it is creating a loop .

 

when HTTP_REQUEST {

 if { [HTTP::uri] starts_with "/xyz" } {

 HTTP::redirect "https://abc.com/xyz"

 }

 elseif { [HTTP::host] eq "abc.com" } {

 HTTP::redirect "https://bbc.com"

 }

}

      Hi, sorry my delay.

      Let me try another option besides our friends.

      Do you need to redirect only when host is abc.com and path starts with /xyz?

       

      e.g.

      1. http(s)://abc.com/xyz - Goto https://bbc.com/xyz

      2. http(s)://abc.com/xyz/abc - Goto https://bbc.com/xyz/abc

      3. http(s)://abc.com/xyzabc - Goto https://bbc.com/xyzabc

      4. http(s)://abc.com/xyz?param=value - Goto https://bbc.com/xyz?param=value

      5. http(s)://abc.com/Xyz - Do nothing

      6. http(s)://abc.com/abc/xyz - Do nothing

      7. http(s)://bbc.com/xyz - Do nothing

       

      Code:

      when HTTP_REQUEST {
  if { [HTTP::host] eq "abc.com" && [HTTP::uri] starts_with "/xyz" } {
    HTTP::redirect "https://bbc.com[HTTP::uri]"
  }
}

      Regards.

    You can try below irule. which will help to achieve your requirements.

    when HTTP_REQUEST {
	if { ([string tolower[HTTP::host]] equals "abc.com") and ([HTTP::uri] starts_with "/xyz") } {
		HTTP::redirect "https://[HTTP::host][HTTP::uri]"
	}
	elseif {[string tolower[HTTP::host]] equals "abc.com")} {
	HTTP::redirect "https://bbc.com" 
		}
}

    Let us know if any issue.

    Try this:

    when HTTP_REQUEST {
    if { ([HTTP::host] equals "abc.com") } {
	if { (not [HTTP::uri] starts_with "/xyz") } {
	HTTP::redirect "https://bbc.com" 
	}
    }
}
