when we are attempting to download files (DOC, XLS, JPG, PDF) from our application, the IE file download dialog hangs.
ASP.NET 2.0 / IIS with Integrated Windows Authentication
The events are:
Click button to download file
Postback occurs which retreives file and creates response
Browser receives response header and body of correct size
Browser raises file open/save/cancel dialog.
Regardless of whether choosing open / save...
File Download Progress Dialog appears but data doesn't get populates (e.g. filename / size / progress)
User can cancel otherwise will stay at dialog until session times out.
If the user chose Save then they will never get the option to choose where the file should be saved to.
The files being downloaded are very small (~20-50K)
Having tested the firewall/AV etc we have identified the problem as being with Passlogix Single Sign On (SSO, now Oracle ESSO).
When SSO is turned on, the file download always fails. If shutdown then the file download always succeeds.
The file download succeeds in Firefox but not in IE 6.0SP2. I believe because SSO uses a plugin for IE which isn't present in Firefox.
I've raised this as a new question as the previous question I found on this issue didn't have a solution...
Can anyone help?
