HTTP::host to match all subdomains of a domain




I want to write an Irule to redirect http to https for all subdomains in a particular domain. I want to do this because we host many domains on that VS and only one of the domains will have encrypted communication. The VS I will redirect the https traffic to, will serve * certificate.



In short when http request comes on VS 1 port 80, I want to check if the http::host is subdomain of, if yes, I want to redirect it to https to VS 2 which has the right certificate.

    think you want something like:


    when HTTP_REQUEST {


    if {[string tolower [HTTP::host]] contains ""}{


    HTTP::redirect "[HTTP::uri]"




  • Here's another option that redirects any subdomain for and preserves the requested host and URI in the redirect:

    when HTTP_REQUEST {
    if {[string tolower [HTTP::host]] ends_with ""}{
    HTTP::redirect "https://[HTTP::host][HTTP::uri]"
