Persistence based on XML data

It has been a while since I tested this iRule out. However, I have used it in the past successfully in 10.x and 11.x code version. The code provides persistence based on jsession id for GET request and xml data for POST request.

You would have to alter the code to suit your specific needs:

when HTTP_REQUEST {

set HOST [string tolower [HTTP::host]]

set SRCADDR [IP::remote_addr]

if { $HOST contains ".v." }{

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

set SESSIONID [findstr [HTTP::uri] "uuid=" 5 20]

set KEY [crc32 $HOST$SESSIONID]

persist hash $KEY 30

} elseif { (([HTTP::method] equals "POST") and ([HTTP::uri] contains "/amm/ampxml.jsp")) } {

 if {[HTTP::header "Content-Length"] ne "" && [HTTP::header "Content-Length"] <= 1048}{

  set CONTENT [HTTP::header "Content-Length"]

 } else {

   set CONTENT 1048

 }

 if { $CONTENT > 0 } {

  HTTP::collect $CONTENT

 }

} elseif { $HOST contains ".suit.domain.com" } {

pool POOL-suit

set KEY [crc32 $HOST$SRCADDR]

persist hash $KEY 14400

} elseif { $HOST contains ".suit.vf.com" } {

pool POOL-vf-suit

set KEY [crc32 $HOST$SRCADDR]

persist hash $KEY 14400

}

}

}

when HTTP_REQUEST_DATA {

if { (([HTTP::method] equals "POST") and ([HTTP::uri] contains "/amm/ampxml.jsp")) } {

set HOST [string tolower [HTTP::host]]

set SESSIONID [findstr [HTTP::payload] "uuid=" 5 20]

set KEY [crc32 $HOST$SESSIONID]

persist hash $KEY 30

}

}
