EmployeeOK....Thanks a bunch for the help. I understand how it obtains the string and replaces it.
I made a couple of tweaks to the script below:
when HTTP_REQUEST {
log local0. "Inside Request"
if { [HTTP::host] contains "dev.integration.services.7-5.identifythebest.com" } {
if {[HTTP::method] eq "POST" && [HTTP::header value Content-Type] contains "text/xml"}{
log local0. "Inside IF"
HTTP::collect [HTTP::header Content-Length]
HTTP::header remove "Accept-Encoding"
HTTP::collect
}
}
}
when HTTP_REQUEST_DATA {
log local0. "Inside Request_data"
set offset [string first {"SSN">} [HTTP::payload]]
set length [expr {[string first {<} [HTTP::payload] $offset] - $offset}]
log local0. "Offset $offset length $length"
log local0. "Replacing [HTTP::payload $offset $length]"
log local0. [HTTP::payload]
HTTP::payload replace $offset $length {"SSN">--}
}
Now I get the following output:

From looking at a packet capture the whole post is in one packet, but the output of the payload appears truncated. any advice?
