NimbostratusHow to ignore case

Ugh, try not to use regular expressions. They are a performance monster.
You can also use the "-nocase" option to several of the string commands (like: string compare). We've also added support for this option to "string first" which is not documented on the Tcl site.
For example:
if { [string first -nocase "foo" [HTTP::uri]] } {...}This finds the first occurance of "foo" regardless of case in the uri.
The advantage of using the -nocase option is that a copy of the string is not made, thus making it perform faster.
