Formatting irule from 4.x to 9.x question

Hi All,

What I have below is an i-rule i created for the bigip version 4.x, however when I tried to format this to work on

the 9.x platform I'm having issues with the regular expression converstion and don't know what the syntax for 9.x is.

If anyone can provide any guidance and feedback, this would be greatly appreciated. 



if (http_host == "www.abc.com" and http_uri matches_regex "/[pP][oO][rR][tT][aA][lL]") {
   redirect to "www.new-redirect.com/portal/index.html"
}
else {
   use pool WEBSERVER_POOL
}

Thanks!

    Here is a 9.x equivalent: 

     
 when HTTP_REQUEST { 
    if {[string tolower [HTTP::host]] eq "www.abc.com" and [string tolower [HTTP::uri]] eq "/portal") { 
       HTTP::redirect "www.new-redirect.com/portal/index.html" 
    } else { 
       pool WEBSERVER_POOL 
    } 
 }

    Well, I'm guessing the rule as you defined it there is going to error out. You're using parens () instead of curly braces {} around the if clause.

     

     

    Does that help at all?

    Hi Aaron,

     

     

    The "portal" should not be case-sensitive, i.e. so if a user connects with http://www.abc.com/PoRtAl using mix case letters (capital and lowercase) they should get redirected to the new url. Will this work? or do i need to use the following code below?

     

     

    if { [regexp -nocase {^/portal} [HTTP::uri]] } {

     

     

     

    Thanks!

    The string tolower will strip case so the regex is unnecessary.
