Hi, I installed the mod_dav in my local apache, to try if it shows the same symtoms, and found some interesting things. 1. Word opens documents not writeprotected on the apache DAV-store, even if they are not writable !!! 2. By accident I had the executable flag set on a htm-file, this file is opened writeprotected !!! This is reproduceble, if you unset the x-flag it is opened in readwrite mode. I took a log of both situations: the only difference I could find was in the response to the GET /dav/testdocweb.htm HTTP/1.1 Accept-Language: de, en-us;q=0.2 If-None-Match: "1cb27-8ce-3bf6bf01" Translate: f User-Agent: Microsoft Data Access Internet Publishing Provider DAV Host: 10.2.1.1 Connection: Keep-Alive wich in the readwrite case is: HTTP/1.1 200 OK Date: Sat, 17 Nov 2001 19:50:19 GMT Server: Apache/1.3.19 (Unix) (SuSE/Linux) mod_python/2.7.2 Python/2.0 DAV/1.0.2 Last-Modified: Sat, 17 Nov 2001 19:50:08 GMT ETag: "1cb25-8fb-3bf6bf70" Accept-Ranges: bytes Content-Length: 2299 Keep-Alive: timeout=15, max=99 Connection: Keep-Alive Content-Type: text/html <html xmlns:o="urn:schemas-microsoft-com:office:office" .... rest of document and in the writeprotected case HTTP/1.1 200 OK Date: Sat, 17 Nov 2001 19:28:14 GMT Server: Apache/1.3.19 (Unix) (SuSE/Linux) mod_python/2.7.2 Python/2.0 DAV/1.0.2 Keep-Alive: timeout=15, max=99 Connection: Keep-Alive Transfer-Encoding: chunked Content-Type: text/html 8fb <html xmlns:o="urn:schemas-microsoft-com:office:office" .... rest of document. in this case the document is fetched a second time, after unlocking. which is also the case, when fetching a htm-file from Zope-Dav storage here is the get for a doc-file: GET /test/testdoc11111111.doc HTTP/1.1 Accept-Language: de, en-us;q=0.2 If-None-Match: ts06033018.5 Translate: f User-Agent: Microsoft Data Access Internet Publishing Provider DAV Host: a.b.de:9800 Connection: Keep-Alive Authorization: Basic xxxxxxxx= and here the response: HTTP/1.1 200 OK Server: Zope/(Zope 2.4.3 (binary release, python 2.1, linux2-x86), python 2.1.0, linux2) ZServer/1.1b$ Date: Sat, 17 Nov 2001 21:38:41 GMT Accept-Ranges: bytes Content-Type: application/msword Content-Length: 19456 Last-Modified: Sat, 17 Nov 2001 21:36:58 GMT it follows the binary doc-file here is the get for an htm-file: GET /test/testweb1.htm HTTP/1.1 Accept-Language: de, en-us;q=0.2 Translate: f User-Agent: Microsoft Data Access Internet Publishing Provider DAV Host: a.b.de:9800 Connection: Keep-Alive Authorization: Basic xxxxxxxxxx= and the response: HTTP/1.1 200 OK Server: Zope/(Zope 2.4.3 (binary release, python 2.1, linux2-x86), python 2.1.0, linux2) ZServer/1.1b$ Date: Sat, 17 Nov 2001 21:38:12 GMT Content-Type: text/html Content-Length: 2703 The only thing which is not there in the writeprotected cases in the response is the "ETag:" and the "Accept-Ranges: bytes", perhaps that tells something to the wizards of the HTTP-protocol ;-) Mit freundlichen Grüßen Joachim Schmitz AixtraWare, Ing.
