Problems with Owncloud WebDAV over Apache Reverse Proxy




I have a working OC9.1 installation on Ubuntu 16.04. My problem is concerned to WebDAV-Access especially from Windows-Systems.

I have the following Apache reverse-proxy statement for redirecting Traffic to my OC-Server:

  ProxyPass / http://oc-ip-address/
  ProxyPassReverse / http://oc-ip-address/

The configuration works well for WebAccess and also for Windows 10 Webdav-Client. WebDav-Client in Windows 7 is not working even after having tried the workaround described in OC-documentation.

So I tried another Reverse-Proxy configuration as follows:

  ProxyPass / http://oc-ip-address/remote.php/webdav/
  ProxyPassReverse / http://oc-ip-address/remote.php/webdav/

This configuration works for Windows 10 and Windows 7 but now I concider some restrictens: first I cannot rename Files in WebDav-Share and Files are opened in MSOffice as ready-only. On my first proxy-configuration this both is working well but with the problem that Windows 7 systems cannot connect. Also other third-party WebDAV-Clients have now problems to connect in this second scenario.

Has someone an idea how I should modify my reverse-proxy configuration to have a fully working WebDAV environnement with OC for Windows and other clients?

Thanks for any help
