irule redirect

I am having trouble with creating an irule that will redirect when url is received and redirect it to dropping the www from the url.



thanks much, Ed Lane

    All you'd need is:

    when HTTP_REQUEST {
      if {[HTTP::host] equals ""} {
        HTTP::redirect "http://[string trimleft [HTTP::host] 'w.']"

    This will strip any "w" or "." characters from the left of the string. It basically eats all characters found within the single quotes, w. in this case, until it gets to the first character that isn't one of those two values.

  • string trimleft is a novel solution Colin. And it seems to perform as well as a string range command. Nice work :)
