STREAM::max_matchsize - HELP - Urgent

One of the F5 expert was able to help write the script, We are running version 9.3.

 

 

Production iRule

 

when HTTP_REQUEST {

 

set uri [string tolower [HTTP::uri]]

 

if { ($uri contains "/global/") }

 

{ pool acecomm }

 

elseif { ($uri contains "/name1/") or

 

($uri contains "/name2/") or

 

($uri contains "/blah/")

 

}

 

{

 

if { $uri contains "/hscs.asmx" } {

 

pool acecomm

 

Change the URI of the request, preserving the query arguments, if any.

 

set args [findstr $uri "?"]

 

HTTP::uri "/global/hscs.asmx$args"

 

 

if {[HTTP::method] equals "POST"} {

 

Determine what the original path was

 

set origpath [findstr $uri "/" 1 "/"]

 

 

Determine the search regex (case-insensitive)

 

set search ""

 

set index 0

 

while {$index < [string length $origpath]} {

 

set char [string index $origpath $index]

 

set search "$search\[$char[string toupper $char]\]"

 

incr index

 

}

 

 

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]"

 

}

 

}

 

}
