I'm uploading GPX files to the dev server using Apache httpclient-4.1.jar and am receiving unclear errors and HTTP-500 status.

Executing the same upload with a perl script succeeds. Tracing the procedure with Wireshark shows only a major difference in the added Content-Type and Content-Transfer-Encoding in the Mime entities.

Attached the network traces to api06.dev.openstreetmap.org using Java and Perl.

Thank for lookin into this.

This appears to be an issue with rack - it treats any field in a multipart/form-data submission which has a content-type as a file which confuses the upload code which only expects the actual GPX data to be a file.

It looks like it is fixed in rack 1.2.1 but rails 2 still uses 1.1.0 so we're probably stuck with this until we can manage to go to rails 3.

Okay, thanks for clearing that up. I'll adjust the upload on the client side.

http-client offers a quick fix client-side:
A constructor parameter allows httpclient changes the behavior as desired.

new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
