This works:
when HTTP_REQUEST {
Don't allow data to be chunked
if { [HTTP::version] eq "1.1" } {
if { [HTTP::header is_keepalive] } {
HTTP::header replace "Connection" "Keep-Alive"
}
HTTP::version "1.0"
}
}
when HTTP_RESPONSE {
Get the content length so we can request the data to be
processed in the HTTP_RESPONSE_DATA event.
if { [HTTP::header exists "Content-Length"] && [HTTP::header "Content-Length"] < 1048577 } {
set content_length [HTTP::header "Content-Length"]
} else {
set content_length 1048576
}
log local0.info "Content Length: $content_length"
if { $content_length > 0 } {
HTTP::collect $content_length
}
}
when HTTP_RESPONSE_DATA {
if { [HTTP::payload] contains "Microsoft OLE DB Provider for SQL Server error"}{
log local0. "found OLE DB Error in response"
HTTP::redirect http://www.domain.com/error.asp
}
HTTP::release
}
Your guidance has been much appreciated.
