iRule to Add Trailing Slash Except for Extensions

Hello, I have an iRule that I am using to direct requests to a specific pool based on the URI: when HTTP_REQUEST { set uri [string tolower [HTTP::uri]] if {[HTTP::uri] starts_with "/apps"}...

    Hello,

    Considering that the resource will only have the dot char to extensions, I do this way:

    when HTTP_REQUEST {
    if { not ( [HTTP::path] ends_with "/") && not ( [URI::basename [HTTP::uri]] contains "." ) } {
        # Append slash and keep querystring when it exists
        HTTP::uri [HTTP::path]/[expr { "[URI::query [HTTP::uri]]" eq {} ? {} : "?[URI::query [HTTP::uri]]" }]
    }
    if { [string tolower [HTTP::uri]] starts_with "/apps" } {
        pool ProxyPass_DEV_pool_2
    }
    else {
        pool ProxyPass_DEV_pool_1
    }
}

    Where:

    1. "/apps" will become "/apps/" internally;
    2. "/apps?param=value" will become "/apps/?param=value" internally;
    3. "/test.html" and "/test.html?param=value" remais the same. 

    I hope it helps.

    Regards

Thanks cjunior! This worked well with only one minor issue. It looks like it is appending the / regardless if it the / is there or not. Is there a way to make the statement to say "if not contains "." AND does not end with "/", to add the "/"?

 

Thanks!
