Okay, we're using dojo.io.iframe to upload a file. I've been reading about the many different ways the situation can get "access is denied" errors, but I'm still stumped. Here are some details:
- dojo 1.6.1 (23843)
- IE 9.0.8112.16421 on Windows 7
- Strangest part: To get to the upload page, the user clicks a link in an email. I get the error when I open gmail in IE and click the link then submit the form, but it doesn't happen if I copy and paste the link into IE and submit the form.
- Nothing cross domain. However the address is an ip address, not a hostname or domain name.
- The error happens on the form.submit() line in the dojo.io.iframe _fireNextRequest() function. So it can't be caused by anything in the response from the server.
This exact same code works just fine in IE on other pages and when I copy and paste the link instead of following it through gmail.
