String Map Fail?

Argh. Can't seem to edit out all that MS crap up there, because I copied this in from an email.     I'm trying to build a function allowing search-and-replace of substrings within a URI.   ...

I'm trying to build a function allowing search-and-replace of substrings within a URI.

 

 

Class:

 

 

class URI_STRING_REPLACE_LIST {   "/coupons/" { "/promotions/offers/coupons/signin.go" }}

 

 

 

 

Rule:

 

 

 

 

when HTTP_REQUEST {     set urisearch ""    set urireplace ""    set newuri ""    set urisearch [class match -name $httpuri contains URI_STRING_REPLACE_LIST]    set urireplace [class match -value $urisearch contains URI_STRING_REPLACE_LIST]                log local0.info "URI-Replace1 Search: $urisearch Replace: $urireplace"                if { ( ( $urisearch ne "" ) and ( $urireplace ne "" ) ) } {                                set $newuri [string map [list $urisearch $urireplace ] $httpuri]                                log local0.info "URI-Replace2 New: $newuri URI: [HTTP::uri]"                                set HTTP::uri $newuri                                return                } }

$urisearch and $urireplace are matching, the string map to set $newuri (though I thought I was seeing it work in the logs earlier) is failing. I tried adding list to the string map statement after finding it referred to in another thread here, but it doesn't seem to help. I'd also tried setting HTTP:uri with the string map directly, but added $newuri trying to troubleshoot. Any ideas why string map doesn't seem to work, or something to use instead?
