Here is an overview of my system configuration:
- Domino 6.5.3 is installed on an Intel box running Server 2003. This machine is on our "inside" and is not accessible from the internet.
- IIS 6.0's SMTP server is running on a seperate machine in our DMZ. It is accessible from the internet.
- Domino is configured to send and receive mail through the IIS machine.
- The IIS machine is also configured as a reverse proxy for Domino Web Access. This was accomplished by using the WebSphere plugin that shipped with Domino and the Web Access Redirect database. (iwaredir.nsf)
Web Access works flawlessly until you try to download an attachment that has a space in the file name. In Firefox, I this error message:
"Http Status Code: 400
Reason: Unknown or unsupported protocol version." Also, the URL gets reformated. The spaces in the file name have been replaced with "%20." Manually editing the URL to the proper file name does nothing. It just replaces the spaces with %20.
Internet Explorer just declares that it is unable to open the file.
I can rename the attachment inside of the Notes client and remove the spaces. This fixes the problem but it is obviously not the solution!
I have spent several hours on the phone with IBM and been shuffled to different departments. The end result is always a followup e-mail with a link to Websphere installation / configuration instructions (which I have read and followed). They also choose to blame IIS. Right now, I am out of ideas.
I appreciate any help that you folks can give.
