They're making the request for a SWF file from another SWF file, they
stated that they did not see a way to change the Accept header for
that request. What they're really asking to do is to disable gzip
compress for the SWF mimetype (which to me seems odd that google would
be doing, since just like most images, its typically already
compressed for size). Its not that the flash player can't accept a
gzip'd SWF file, its that it won't give loading progress events -
whether that's because of how the browser or flash handles the
request, who knows.

Is there a way to disable gzip compression for certain mimetypes? If
not, is there documentation for what mimetypes the front end servers
will gzip? Perhaps they could try serving their SWF files with a
general mimetype like application/octet-stream if that's not gzip'd by
the front end servers - the effect on the browsers and flash's
interpretation would have to be tested, but I imagine they'd be
tolerant. Both the python and java configuration have ways to specify
the mimetype served for specific static urls / file extensions.
