Determine what the original path was
set origpath [findstr $uri "/" 1 "/"]
Determine the search regex (case-insensitive)
set search ""

Look for /*/hscs.asmx and replace * with "global"
(if you change "global" here you need to change the hard-coded length of 6 below)
Note that this does not fix the Content-Length so we need to do that below
STREAM::expression "@/$search/\[Cc\]\[Oo\]\[Mm\]\[Pp\].\[Aa\]\[Ss\]\[Mm\]\[Xx\]@/global/hscs.asmx@"
STREAM::enable
Store original content-length for POST data
set origlen [HTTP::header "Content-Length"]
Assume replacement string ("global") is 6 characters long, determine difference in
length between "global" and the replacement path
set length_change [expr {6 - [string length $origpath] } ]
Set new content length, assuming the stream profile performed exactly one replacement
HTTP::header remove "Content-Length"
HTTP::header insert "Content-Length" [expr {$origlen + $length_change}]
log local0. "search path $search"
log local0. "origpath=$origpath, change=$length_change, origlen=$origlen"
log local0. "origpath=$origpath, Content len after: [HTTP::header Content-length]"
}
