iRule resulting in too many redirects

The way it's written, it seems like it will always send a redirect response. I assume you probably would like it to NOT redirect sometimes.

In what way do you want the BIG-IP tell the difference between when you want it to redirect and when you don't?

Lucas_Thompson did get me thinking about the flow. I moved the "HTTP::redirect $new_url" to HTTP_RESPONSE thinking that it might be because it is redirecting to itself and each request was doing the same thing over and over. It didn't work, but the logic to me seems sound. 

Should the HTTP::redirect be in the response?

Am I just mucking up the logic here? Should I check to make sure the incoming path is correct and if not, then redirect?

I rewrote the iRule to add the logic that Lucas_Thompson referenced to determine when I need to redirect. I can't find anything wrong with the code. However, I get ERR_CONNECTION_RESET.

For added information, I am using this iRule in conjunction with Universal persistence.

The new code is below.

when HTTP_RESPONSE {

## PERSISTENCE

    # If the JSESSIONID exists, we'll pass the cookie along

    if { [HTTP::cookie exists "JSESSIONID"] } {

        persist add uie [HTTP::cookie "JSESSIONID"] 86400

    }

## REDIRECT

    # Check if the request path is not "/pc/service/SSOLogin"

    if { $url_redirect } {

        # Redirect to the new URL

        HTTP::redirect $new_url

    }

}

when HTTP_REQUEST {

## PERSISTENCE

    # If the JSESSIONID exists, we'll maintain that persistence

    if { [HTTP::cookie exists "JSESSIONID"] } {

        persist uie [HTTP::cookie "JSESSIONID"]

    }

## REDIRECT

     # Check if the request path is already "/pc/service/SSOLogin"

     # If so, set the url_redirect to false. If not, set it to true.

     if { [string equal [HTTP::uri] "/pc/service/SSOLogin"] } {

          set $url_redirect 0; 

     } else {

          set $url_redirect 1; 

          # This grabs the base URL from the incoming request

          # For example, https://my.site.com/some/path the base_url is set to https://my.site.com

          set base_url "https://[HTTP::host]"

          # Defining the new path

          set new_path "/pc/service/SSOLogin"

           # Construct the new URL

           # For example, https://my.site.com/pc/service/SSOLogin

           set new_url "$base_url$new_path"

     }

}

I think my real problem is that I need to set a 301 permanent redirect.
