flash and webservices problem; possible solve to communication errors

Posted on | July 25, 2008 | No Comments

We’ve been having many problems lately with our flash applications, communicating with webservices. Since a couple of weeks (maybe even months?) our flash application did not get a response from a webservice. Therefore, the request was not closed properly and we got our fallback timeout window continuously.

And then I read a snippet from this blogpost that it might have to do with the crossdomain policy file settings. I checked the section concerning http-request-headers, inserted these into the crossdomain policy file, and everything worked as normal immediately.

I don’t have a definite answer yet to why this all happened, and why one has to specify the headers next to the domains now, but I suspect a (security?) update in the flash player lately could have triggered this effect.
