embedding a flash file

[fnustle]

I've embedded a flash file into an assembly:

[assembly: WebResourceAttr ibute("Namespac e.main.swf", "applicatio n/x-
shockwave-flash")]

But when I try to reference it on a web page:

<object codebase="http://download.macrom edia.com/pub/shockwave/
cabs/flash/swflash.cab"
height="100" width="100" classid="clsid: D27CDB6E-
AE6D-11cf-96B8-444553540000">
<param name="src" value="/WebResource.axd ?d=bYC1eHVfsX9X-
yIbBHXWbUVMFGQV vrZPQF0kP_mR3y4 x7BaHrIsA2V8j5M oYYcTy0&amp;t=6 330725220393750 00">
</object>

it never loads. The page just times out.

When I try to load the resource directly in the browser it shows that
the content-type is not set and that the content-length is 0.

I know the webresource string is correct and pointing to an existing
resource because it works for an image file.

Is this a known issue or am I doing something wrong?
