ServerPushSession and XML parsing error in Firefox [message #1753154]

Hi,
in Firefox (51.0.1) we see log messages and an increasing error count which seems to be caused by the ServerPushSession GET requests. Those requests do not seem to return any content (responses are 0 bytes or 1 bytes), but Firefox attempts to parse the result as XML. As indicated in the following discussion
https://github.com/rapid7/le_js/issues/24
this seems to be due to a bug in Firefox, where responses with no Content-Type header are handled as "xml" instead of "octet-stream".

Wouldn't it be possible to set the response Content-Type in the
org.eclipse.rap.rwt.internal.servpush.ServerPushServiceHandler to a value which makes Firefox behave correctly (e.g. application/octet-stream)?

Kind regards,
Gunnar Adams

It would. RAP already sets cache control headers in there to fix IE bugs.
It should also be possible to create a servlet filter to add them as well, which means you could fix it immediately without patching and rebuilding RAP.

Hi,
could you please open a bugzilla about this issue.We set several response headers in ServerPushServiceHandler. To speed up the fix you can contribute your proposal through Gerrit [1].
