URI Tracker - Question - ERROR: undefined procedure: swith][swith -glob [string tolower [HTTP::uri]]

Question

URI tracker code is driving me nutts. I dont know if my backets are screwed up or if my HTTP::uri is screwed. For awhile, I was getting a cross bracket error, but after using Notepad++, I THINK i got them all. Now Im getting the attached error now. has anyone else used the Link tracker and had issues with the code parsing?&nbsp;    when HTTP_REQUEST {

set TABLE_LINK "LINK_TRACKING_[virtual name]";
set TABLE_FILTERS "LINK_TRACKING_FILTERS_[virtual name]";

swith -glob [string tolower [HTTP::uri]] {

There's a } missing before the "/linkcleardata".&nbsp;
I don't have an F5 on me at the moment, so i can't confirm if there are any other errors.&nbsp;
HTH.&nbsp;

Hi Smiley,
reworked your code formatings and catched almost a dozend TCL/HTML glitches.
I've changed a little bit your sytax to rely more on substitution instead of switching between "" and {} escaped $content.&nbsp;The new code will only leave HTML when you have to [if] or [foreach] dynamic HTML code.
