Re: Strange WebDAV behavior on MKCOL for 1 client only

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

It looks like a problem with the implementation or configuration in the client.
The actual source of your 400 error is this:
[auth_digest:error] [pid 3880:tid 1132] [client yyy.yyy.yyy.yy:61411] AH01786: uri mismatch - </webdav/dir1/dir2/dir3/dir4/dir5/dir6> does not match request-uri </webdav/dir1/dir2/dir3/dir4/dir5/dir6/>

This is because your Authorization header has - as the error message clearly states - a mismatch.

On your working connection:
Authorization: [...] uri="/webdav/dir1/dir2/dir3/dir4/dir5/dir6/", [...] 

On your broken connection:
Authorization: [...] uri="/webdav/dir1/dir2/dir3/dir4/dir5/dir6", [...]

Note the missing trailing slash in your authorization header.
I suspect if you figure out why you are getting that, everything will start working.

Try mod_dumpio or a packet capture to see what else is different about the request.

Hello,

I have Apache mod_dav running on Windows 2012.  

When a webDAV enabled application connects and tries to MKCOL on a directory that already exists, it receives an HTTP 400:

____________________________________________________________________________

yyy.yyy.yyy.yy - username [07/Aug/2017:11:00:03 -0700] "MKCOL /webdav/dir1/dir2/dir3/dir4/dir5/dir6/ HTTP/1.1" 400 226
____________________________________________________________________________


However, all other clients are receiving an HTTP 405 when they issue a MKCOL for a directory that already exists:

____________________________________________________________________________

xxx.xxx.xxx.xx - username [07/Aug/2017:12:32:16 -0700] "MKCOL /webdav/dir1/dir2/dir3/dir4/dir5/dir6/ HTTP/1.1" 405 253
____________________________________________________________________________


The application is dependent on receiving a 405 in this scenario, has anyone else had this situation before?
