Sorry for only replying now, I was away. Let me know if  need to repost my original message.

Yes, see the attached program. I also included a couple of images that fails _most_ of the time.

Uhm, the attached example simply tries to upload a few image files (evaluate the function test-upload). *Important*: From Linux to XP/Linux all uploads work for both secure and non-secure attempts. From XP only non-secure uploads work. Secure uploads from XP will work about 5% of the time. I even tried it on different machines.

No, I removed trivial-ldap completely in the example.

Uploads from
 LispWorks (Win32) to LispWorks or SBCL on Linux fails.
 LispWorks (Win32) to LispWorks on Win32 fails.
 SBCL (Linux) to Win32 LispWorks works.
 SBCL (Linux) to LispWorks and SBCL on Linux works.
 LispWorks (Linux) to LispWorks and SBCL on Linux works.
I don't have another CL for Win32. LispWorks 5.0.2 was used in all instances.

No, it does not seem to make a difference.

Thanks in advance.
