Hello, I think you are combining curly braces with variables and this avoids their expansion. So, it should be something like this:

HTTP::respond 302 noserver Location "$new_destination[string map "$web_uri [HTTP::uri]" [HTTP::uri]]"

However, I think that the result will not be what you expect with those combinations, then, as a first shot, you could do like this:

HTTP::respond 302 noserver Location "$new_destination[string range [HTTP::uri] [expr [string len $web_uri]+1] end]"

Anyway, why do you not do that by using "data group" and "class match" to avoid iteration in their arrays? Maybe it could be more easy to do.

Another point,is the second part that seems to have the same effect when the operator "equals" and "starts_with", will have the same final execution, then it seems to me to be redundant and unnecessary to use the first operator "equals". Sorry if I did not analyze as a whole.

I think that's all, I hope I have helped you!

Regards.
