NimbostratusOops. For got to explain the bracket thing. What specifically was going on was this:
[HTTP::host][HTTP::uri] evaluates those two variables as they're coming in from the request. It'll look something like: 10.8.224.44/dir32/, for example.
Now, that second set of brackets around it: [ [HTTP::host][HTTP::uri] ]
...was actually trying to evaluate the string returned from the inner host and uri variables after they were returned as strings, so it threw that error in your logs. The TCL interpreter tried to run:
[ 10.8.224.44/dir32/ ] as a command, which is invalid.
I hope this makes sense. By simply removing that outer set of brackets the findclass command was able to evaluate your lookup correctly.
