How to set up git over apache 2.4 on Windows

How to set up git apache 2.4 on Windows

At my first shot I was abl to glone the repo but I wasn’t able to push into the repo. Setting the LogLevel to debug showed: AH01215: Service not enabled: ‘receive-pack’: C:/Program Files (x86)/Git/libexec/git-core/git-http-backend.exe

Googling suggested to enable WebDAV. I doubted that but tried it anyway. Trail and error! It did not work about. The git client showed a 403 -> an access or authentication error.   The authentication triggered something in my mind. So I searched for the auth variable that git uses. Et voilà: Git uses the remote user in a different way.
SetEnv REMOTE_USER $REDIRECT_REMOTE_USER
The following set up is not secure, just for local testing. It requires  a http authentication ;)

<VirtualHost *:80>
    ServerName git.local.apachehaus.de
    DocumentRoot "/Users/mario/work/git"
    CustomLog "C:\nul" common

    SetEnv GIT_PROJECT_ROOT /Users/mario/work/git
    SetEnv GIT_HTTP_EXPORT_ALL true
    SetEnv REMOTE_USER $REDIRECT_REMOTE_USER

    ScriptAliasMatch "(?x)^/(.*/(HEAD | info/refs | objects/(info/[^/]+ | [0-9a-f]{2}/[0-9a-f]{38} | pack/pack-[0-9a-f]{40}.(pack|idx)) | git-(upload|receive)-pack))$" "C:/Program Files (x86)/git/libexec/git-core/git-http-backend.exe/$1"
