URL host rewrite based on URI

Hi Anish,

 

 

Can you give a few more exact examples of when you want to redirect the client request?

 

 

Is the general logic, check the first directory in the URI (/product1/ or /product2/) and see if it starts with the literal string "product" and then check if it does not match the hostname's first field (product1.xyz.com)?

 

 

I assume "product" isn't the actual word you want to look for. But is that word always the same that you want to look for in both the URI and host header value?

 

 

Thanks,

 

Aaron

Hey Aaron

 

 

Let me try to explain again

 

 

The main domain of the site www.xyz.com is setup on the f5 as a virtual server and it has various sub-sections. One of the sections is product1, which usually users can access as http://www.xyz.com/product1 and this is also how its indexed in various search engines as well.

 

 

Let's say for SEO purposes I needed to create a sub-domain product1.xyz.com with a host header entry in IIS so that requests to http://www.xyz.com and http://product1.betus.com return the same response i.e. content and http://www.xyz.com/product1 is the same as http://product1.xyz.com/product1 (product1 is a subdirectory in the WebRoot).

 

 

So, basically what I am trying to achive is that when a request comes to /product1 on host http://www.xyz.com/[HTTP::uri] it should get redirected to http://product1.xyz.com/[HTTP::uri]

 

 

However, since, its a redirect, now any subsequent requests on the page (for e.g.) if the user clicks on /product2 (another of the subsections) the browser address bar shows http://product1.xyz.com/product2. This is what I don't want to happen. Either the Address bar should revert to the default host URL i.e. http://www.xyz.com/product2 or if I have another rule then redirect to http://product2.xyz.com/product2.

 

 

I will create as many host-headers that are needed for product1, product2 etc.

 

 

Hope I have not confused you any further. Thanks again

 

 

Regards

So maybe something like this?

 
 when HTTP_REQUEST { 
  
     Check if the subdomain starts with www. or is null 
    if {[string tolower [HTTP::host]] starts_with "www." or [HTTP::host] eq ""}{ 
  
        Exit this event in this rule 
       return 
    } 
    log local0. "Host didn't start with www: [HTTP::host]" 
  
     Save the first directory in the HTTP path, set to lower case 
    set first_dir [string tolower [getfield [HTTP::path] "/" 2]] 
  
     Check if the first directory matches some pattern like "product" 
    if {not ($first_dir starts_with "product")}{ 
  
        Exit this event in this rule 
       return 
    } 
    log local0. "\$first_dir, $first_dir, matched the pattern check" 
  
     Check if the first directory in the path is not the same as the subdomain 
    if {$first_dir ne [getfield [string tolower [HTTP::host]] "." 1]}{ 
  
          log local0. "Redirecting request to $first_dir.xyz.com" 
          HTTP::redirect "$first_dir.xyz.com" 
       } 
    } 
 }
