Nested Loop for IRules Redirects

Question

Would anyone be willing to review this and see if it can be made more efficient or has obvious errors? I converted a .htaccess file to irules and learned I was much over the maximum character limit. I'm now trying to programmatically capture the same logic. At the same time I am finding there isn't a good way to test these except live.&nbsp;when HTTP_REQUEST {#Start Sorting By Season First set ::season_list [fall* spring* summer* winter*] set ::term_list [100 101 102] set ::professor_list [smith jones smith-jones chaplain]# Loop through the datagroup line by line.foreach season $::season_list {# Log the current line. log local0. "Current \$season: $season"# Compare the element against the string.# If the datagroup entry has a wildcard, it should be listed first in the string compare statement.if {[HTTP::uri] starts_with $season} then {# Found a match, so log it and break out of the foreach loop.foreach term $::term_list {# Log the current line. log local0.

I'm not sure I follow all the logic you're trying to achieve. Can you provide the goals of your iRule separate from the code, and if there is a full version of the iRule, can you post that (sanitized) in a gist on github or here if it'll fit?
