Uploads fail with digest access authentication

[deubeulyou@…]

I can browse allright, but when uploading a file, I get the following error at the end of the transfer: "unbuffered entity enclosing request can not be repeated".

Note that all kinds of file fail, even with small sizes, so this is probably not the same as #2144

Also, this error message appears

Server specs:

• lighttpd and lighttpd mod_webdav 1.4.13-4etch8
• SSL with certificate signed by custom CA
• digest auth

I'll take advantage of reporting this to say thanks for this nice app !

#2144 looks like a duplicate.

Thanks for looking at this ! I can provide a test account on this server if necessary.

A test account would be very welcome.

#2492 is probably a duplicate.

We just had two customers report this error to us against our BingoDisk product. We have a demo account setup where you are able to test against. ​http://demo.bingodisk.com/bingo/ password bingo

This has been resolved using the Use of the 100 (Continue) Status feature of HTTP 1.1. Before sending the entity request body, we check if the server accepts the authentication credentials and only continue if 100 Continue is returned. It looks like this running against Apache2:
