remove www

Problem this snippet solves:

We basically want to redirect www.ecpurchasing.com to https://ecpurchasing.com. Right now the rule in the load balancer simply redirects http to https. External clients that use the Referrer URL for authentication validation only accepts request coming from https://ecpurchasing.com without “www”.

this virtual supports a number of sites using a SAN cert. The SAN cert includes ecpurchasing.com as well as www.ecpurchasing.com but the application needs to receive requests just from https://ecpurchasing.com.

How to use this snippet:

when HTTP_REQUEST { if {[string tolower [HTTP::host]] starts_with "www.ecpurchasing";} { #HTTP::redirect "https://[findstr [string tolower [HTTP::host]] "www.ecpurchasing"; 4][HTTP::uri]" HTTP::redirect "http://[string range [HTTP::host] 4 end][HTTP::uri]" } else { HTTP::redirect "https://[HTTP::host][HTTP::uri]" } }

Code :

when HTTP_REQUEST {
    if {[string tolower [HTTP::host]] starts_with "www.ecpurchasing"} {
       #HTTP::redirect "https://[findstr [string tolower [HTTP::host]] "www.ecpurchasing" 4][HTTP::uri]"
        HTTP::redirect "http://[string range [HTTP::host] 4 end][HTTP::uri]"
    } else {
        HTTP::redirect "https://[HTTP::host][HTTP::uri]"
    }
}

    this seems simple enough but broke my site when i applied it, all https stopped working and i get page cant be displayed. my irule is as follows:

     

    when HTTP_REQUEST {

      if {[string tolower [HTTP::host]] starts_with "www.jarvis"} {

        #HTTP::redirect "https://[findstr [string tolower [HTTP::host]] "www.jarvis" 4][HTTP::uri]"

        HTTP::redirect "http://[string range [HTTP::host] 4 end][HTTP::uri]"

      } else {

        HTTP::redirect "https://[HTTP::host][HTTP::uri]"

      }

    }
