I have no control over the "Response Header". DoMore issues a "HTTP/0.9 200 OK" each time it STREAMs. I can only edit the "Content" of the STREAM.
I can edit these headers when I configure WAMP server, or IIS in windows, but it appears DoMore is using a generic response.
I don't know how that works from your end, but if you want to view the headers, you can get an extension for firefox called "Live HTTP headers 0.17" so you can view them.
I would really like to be able to edit the headers some how, but I figured it was asking an awful lot from you guys, because I don't know that many would use it.
...I don't know enough to be able to dissect where the header is located in the packet using wireshark, but I did find this page that may help:
