IE 6.0 SP1 problems with file upload or multipart post via https

M

Michael Holly

I am having an intermittant error when trying to do a file
upload in my application.

Environment
XP, 2000
IE 6.0 SP1, and other variants (patches).
Request runs through a reverse proxy server which
redirects the request to the proper url.
We are using https.

Description
When attempting the upload. Microsoft IE 6.0 returns
immediately (not a timeout)
with a "Page can not be displayed" error. The browser
does attempt to send the
request. We have verified that there is no traffic coming
form the ip when the
upload is submitted. We are testing with other browsers
to try to recreate the error
All other requests (mixture of GETs and POSTs) to this
site work correctly. My
source for the form is below.

The upload page is a javascript window spawned from the
main application window.



Other references
Internet Explorer does not upload a file to an HTTPS URL
and requires SSL client authentication

Workaround
Make a reference on the page to a image to allow a secure
connection to be authenticated before the
upload is attempted.

I am having the exact same problem, Michael. It is rather frustrating.
I had made some changes to the page to get it to work occasionally,
which it does, but, it is not dependable. Sometimes it works,
sometimes it does not. Rather frustrating!!

And, we did test with other browsers besides IE, and, it works every
single time.
And, the same page in IE, w/o SSL enabled works just fine.

And, to make things even more interested, if we view the page in IE w/
SSL enabled, but, do not click on the "Browse ..." button or enter
anything into the file field, it works every time!!!

If anyone out there has had similar issues and has found a solution,
please, let me know, as I am at my wits end.

TIA
