simple redirection not working as expected - please help

There are two main parts to a common url like "http://website.com."

1. [HTTP::host] is "website.com"

2. [HTTP::uri] is typically "/" for a home page, it's basically the part after the host and before queries, paths, etc.

In your case, you're looking for a URI to equal "website.com" which will never happen. Also, by using HTTP::uri on the line after, you're essentially rewriting the URI on the way to your pool member. The reason you were redirected to https://website.com is because you met your else statement.

Try this:

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

Instead of "eq", you could also use "starts_with" as some clients/browsers will send you hosts like "website.com."
