Flash event errors on IIS7+

Flash app I've built works fine on desktop and on IIS6, but when I upload to IIS7+ it breaks. Most of the app app开发者_JAVA百科ears to work as expected but a crucial test fails. I think it's a custom event that is failing, but I've no idea why when it works perfectly everywhere else.

Anybody else has issues with Flash and IIS7+?

My app is built with Flash CS5 and AS3 for Flash player 10.

BTW it's not a MIME type issue.

Any help appreciated.

Thanks

Barry

Don't use the '+' character in filenames on servers running IIS7+. IIS7 treats these as if they were query strings. So a filename 'hello+world+today.jpg' will be translated into 'hello.jpg?key=world+today'. This sometimes fails silently in Flash without throwing an IOError, assuming you set up to receive one of course.
