when RULE_INIT {

}
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 {
if { [HTTP::header Content-Type] starts_with "text/html" } {
if { [HTTP::header exists "Content-Length"] } {
set content_length [HTTP::header "Content-Length"]
} else {
set content_length 1000000
}
if { $content_length > 0 } {
HTTP::collect $content_length
}
}
}
when HTTP_RESPONSE_DATA {
set resp [HTTP::payload]
(( search resp for body or /body and get the offset ))
(( set first_part substr $resp 1 ))
(( set rest $insert_text[substr $resp
