I may have worked out the reason but not a solution. The Addheader methods adds a new header, but leaves the orginal one. Using web- sniffer.net I was able to see the HTTP Response header containing two content-type header entries. It seems as though, given a choice IE chooses to follow the "image/svg+xml" header, but Firefox chooses the "text/html".
I'm afraid I'm not clever enough to think of a way around this. Quentin ------------------------ Yahoo! Groups Sponsor --------------------~--> Get fast access to your favorite Yahoo! Groups.
