Append characters within Content-Type Header

Hello Crate,

Could you try the following irule

when HTTP_REQUEST {

if { [HTTP::header "Content-Type"] contains "boundary=" } {
    log local0. "Content-Type value BEFORE : [HTTP::header "Content-Type"]"
    set content_type [HTTP::header "Content-Type"]
        if { [scan $content_type {%[^=]=%s} first second] == 2 } { 
            set new_content_type "$first=--$second"
            HTTP::header replace "Content-Type" $new_content_type
            log local0. "Content-Type value AFTER: [HTTP::header "Content-Type"]"
        }
    }
}

Hope it helps

Please give me a feedback

Regards
