URL TRANSLATION
---------------
-'git-http-backend' relies on the invoking web server to perform
-URL to path translation, and store the repository path into the
-PATH_TRANSLATED environment variable. Most web servers will do
-this translation automatically, resolving the suffix after the
-CGI name relative to the server's document root.
+To determine the location of the repository on disk, 'git-http-backend'
+concatenates the environment variables PATH_INFO, which is set
+automatically by the web server, and GIT_PROJECT_ROOT, which must be set
+manually in the web server configuration. If GIT_PROJECT_ROOT is not
+set, 'git-http-backend' reads PATH_TRANSLATED, which is also set
+automatically by the web server.
EXAMPLES
--------
Apache 2.x::
- To serve all Git repositories contained within the '/git/'
- subdirectory of the DocumentRoot, ensure mod_cgi and
- mod_alias are enabled, and create a ScriptAlias to the CGI:
+ Ensure mod_cgi, mod_alias, and mod_env are enabled, set
+ GIT_PROJECT_ROOT (or DocumentRoot) appropriately, and
+ create a ScriptAlias to the CGI:
+
----------------------------------------------------------------
-ScriptAlias /git/ /usr/libexec/git-core/git-http-backend/git/
-
-<Directory /usr/libexec/git-core>
- Options None

-<Files /usr/libexec/git-core/git-http-backend>
- Options ExecCGI

+SetEnv GIT_PROJECT_ROOT /var/www/git
+ScriptAlias /git/ /usr/libexec/git-core/git-http-backend/

-To require authentication for both reads and writes, use a Directory
+To require authentication for both reads and writes, use a Location
directive around the repository, or one of its parent directories:

AuthType Basic
AuthName "Private Git Access"
