Sometimes I use telnet (from linux/unix) to actually test buggy applications, wget/curl are sometimes just too smart. Also: what are the headers? Another thing to test is just copying the file and changing the file extension to something likely unused: .sswwff. Compare the headers received. Web servers and clients should handle any content it doesn't understand as binary data */*. Some clients peek at the content, some peek at the file extension, but I think the correct behavior is to consult the headers content-type, etc. My guess is that it is a combination of local configuration and server/client mismatch.

Same results And it's worse than that. I took a step back and tried the standard starkit distribution. The home page is shown as expected, however, the gif spacer under htdocs/images/Space.gif hangs (same as “my” .swf files). Then I tried to: - add a copy of htdocs/links/README.txt as htdocs/links/LEGGIMI.txt: OK - add a copy of htdocs/links/README.txt as htdocs/links/test.txt: OK - edit test.txt deleting all the content except the first paragraph: OK - same thing except the first 65 chars: OK - same thing except the first 64 chars: HANGS And guess what? The Space.gif it's a 49 byte file So I put a copy of one of the SWFs, which is way bigger than 64B, under htdocs/links and… it hangs as well. -- Giorgio Valoti

Then I browse to http://localhost:8015/ with Safari and when click on Vuvuzela-Button.swf it works as expected. -- David Zolli

Until you use something like telnet, or Tcl's socket to try a raw request, and show us what you typed and the full result, it is hard to help much further. From what I understand, it isn't hanging, it is just returning some headers. Telnet will maybe show some data getting sent.
