HTTPS Request irule

Hi,

 

 

We have VS with SSL client profile and the redirection irule configured for HTTP VS.

 

 

Currently the site www.xyz.com or xyz.com get redirected to https://www.xyz.com due to irule configuration on HTTP VS.

 

 

However when client request for https://xyz.com the redirection is not happening even though the following irule is configured.

 

 

when HTTP_REQUEST {

 

if {[string tolower [HTTP::host]] eq "xyz.co.in" &&

 

[TCP::local_port] == 443 } {

 

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

 

}

 

}

 

 

Kindly help in fixing the issue.

 

 

Appreciate your prompt response and support.

  • [HTTP::host] should return "xyz.com" when https://xyz.com is requested. Try this:

    when HTTP_REQUEST {
        if  { [string tolower [HTTP::host]] eq "xyz.com" } {
            HTTP::redirect "https://www.[HTTP::host][HTTP::uri]"
        }
    }
     

    This iRule needs to go on the https VS, not the http one.

    Notice that you don't need to check the port if you only put this iRule on your 443 VS. Keep in mind, however, that if https://xyz.com results in a certificate error because of a host name mismatch that this error will still be encountered as the request without the www is already being served. Here is a good article on the host name mismatch fun.

  • Hi Brian,

     

     

    Thanks for the response however the applied irule doenst work as required.

     

     

    Whenever we go for URL https://xyz.com it gives Connection reset but when we provide the URI along with it redirect properly such as https://xyz.com/home.aspx.

     

     

    Do let me know any additional modification to be done in irule.

    Would this work for you?

     

     

    when HTTP_REQUEST {

     

    if { [string tolower [HTTP::host]] eq "xyz.com" } {

     

    Check if there is no uri too

     

    if { [string tolower [HTTP::uri]] eq "" } {

     

    HTTP::redirect "https://www.[HTTP::host]"

     

    } elseif { [string tolower [HTTP::host]] eq "xyz.com" } {

     

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

     

    }

     

    }

     

    }

     

     

    Hope this helps,

  • Hi Nathan,

  • Whenever we go for URL https://xyz.com it gives Connection reset but when we provide the URI along with it redirect properly such as https://xyz.com/home.aspx.wondering what result is when running curl.

    e.g.

    [root@ve10:Active] config  b virtual bar list
    virtual bar {
       destination 172.28.19.79:443
       ip protocol 6
       rules myrule
       profiles {
          clientssl {
             clientside
          }
          http {}
          tcp {}
       }
    }
    [root@ve10:Active] config  b rule myrule list
    rule myrule {
       when HTTP_REQUEST {
       if  { [string tolower [HTTP::host]] eq "xyz.com" } {
          HTTP::redirect "https://www.[HTTP::host][HTTP::uri]"
       }
    }
    }
    
  • sorry i forgot to paste the result. 🙂

    [root@ve10:Active] config  curl -Ik https://172.28.19.79 -H "Host: xyz.com"
    HTTP/1.0 302 Found
    Location: https://www.xyz.com/
    Server: BigIP
    Connection: Keep-Alive
    Content-Length: 0
