The UNLOCK Method

The UNLOCK method unlocks a previously locked resource. Here is a sample UNLOCK request:

UNLOCK http://localhost/digestdav/sample.txt HTTP/1.1
Host: localhost
User-Agent: cadaver/0.22.3 neon/0.25.5
Connection: TE
TE: trailers
Lock-Token: <opaquelocktoken:88b89612-42f8-da11-a875-00c09fda2406>
Authorization: Digest username="admin",
  realm="WebDAV Repository",
  nonce="lH7X/9cVBAA=6f52d718e590fa52b2a1bebc8f10b80e7ff5ff98",
  uri="http://localhost/digestdav/sample.txt",
  response="f48d1162f7a5a3ca43d889aabb7f0b73",
  algorithm="MD5",
  cnonce="35e85c14ff49b98c006fd5f39fe93fff",
  nc=00000006, qop="auth"

The Lock-Token header contains the opaque locktoken and if it matches, the resource will be successfully locked with a 204 No Content response:

HTTP/1.1 204 No Content
Date: Sat, 10 Jun 2006 05:29:32 GMT
Server: Apache/2.2.2 (FreeBSD) mod_ssl/2.2.2
  OpenSSL/0.9.7e-p1 DAV/2 SVN/1.3.1 mod_jk/1.2.15
Authentication-Info: rspauth="9049098842761b98fd506e6cd8e06610",
  cnonce="35e85c14ff49b98c006fd5f39fe93fff",
  nc=00000006, qop=auth
Content-Length: 0
Content-Type: text/plain

If the token does not match, this means that the client does not posses the lock and the resource is not unlocked and a 400 Bad Request response is returned:

HTTP/1.1 400 Bad Request
