Converting from 1.4 to 1.1...

Simple answer - set up a packet sniffer (or a proxy server that prints out HTTP headers) and load an applet normally.  See what other servers reply with, and copy them.

I expect there's a few extra things that Opera would like to see, a content length and an expiry date to name but two.

Ok, tried that... Surprising results obtained:

Sending the jar:

Header is: Content-Type: text/html; charset=ISO-8859-1

And that is it. Opera seems happy with that.
Sent via PHP, I get a whole load of extra cache stuff tacked on by the PHP session, then the content type followed by the jar data. So Ive changed the type I send it as to be the 'text/html' (which seems a little crazy, but it works for the jars) and... No joy. 1.3 & Opera still give the same error message while 1.4, Mozilla & Netscape read it just fine.
Wierd...
