DocumentRoot) appropriately, and
	create a ScriptAlias to the CGI:
+
----------------------------------------------------------------
SetEnv GIT_PROJECT_ROOT /var/www/git
SetEnv GIT_HTTP_EXPORT_ALL
ScriptAlias /git/ /usr/libexec/git-core/git-http-backend/

# This is not strictly necessary using Apache and a modern version of
# git-http-backend, as the webserver will pass along the header in the
# environment as HTTP_GIT_PROTOCOL, and http-backend will copy that into
# GIT_PROTOCOL. But you may need this line (or something similar if you
# are using a different webserver), or if you want to support older Git
# versions that did not do that copying.
#
# Having the webserver set up GIT_PROTOCOL is perfectly fine even with
# modern versions (and will take precedence over HTTP_GIT_PROTOCOL,
# which means it can be used to override the client's request).
SetEnvIf Git-Protocol ".*" GIT_PROTOCOL=$0
----------------------------------------------------------------
+
To enable anonymous read access but authenticated write access,
require authorization for both the initial ref advertisement (which we
detect as a push via the service parameter in the query string), and the
receive-pack invocation itself:
+
----------------------------------------------------------------
RewriteCond %{QUERY_STRING} service=git-receive-pack [OR]
RewriteCond %{REQUEST_URI} /git-receive-pack$
RewriteRule ^/git/ - [E=AUTHREQUIRED:yes]

<LocationMatch "^/git/">
	Order Deny,Allow
	Deny from env=AUTHREQUIRED

	AuthType Basic
	AuthName "Git Access"
	Require group committers
	Satisfy Any
	...
</LocationMatch>
----------------------------------------------------------------
+
If you do not have `mod_rewrite` available to match against the query
string, it is sufficient to just protect `git-receive-pack` itself,
like:
+
----------------------------------------------------------------
<LocationMatch "^/git/.*/git-receive-pack$">
	AuthType Basic
	AuthName "Git Access"
	Require group committers
	...
</LocationMatch>
----------------------------------------------------------------
+
In this mode, the server will not request authentication until the
client actually starts the object negotiation phase of the push, rather
than during the initial contact.  For this reason, you must also enable
the `http.receivepack` config option in any repositories that should
accept a push. The default behavior, if `http.receivepack` is not set,
is to reject any pushes by unauthenticated users; the initial request
will therefore report `403 Forbidden` to the client, without even giving
an opportunity for authentication.
+
To require authentication for both reads and writes, use a Location
directive around the repository, or one of its parent directories:
+
----------------------------------------------------------------
<Location /git/private>
	AuthType Basic
	AuthName "Private Git Access"
	Require group committers
	...
</Location>
----------------------------------------------------------------
+
To serve gitweb at the same url, use a ScriptAliasMatch to only
those URLs that 'git http-backend' can handle, and forward the
rest to gitweb:
+
----------------------------------------------------------------
ScriptAliasMatch \
	"(?x)^/git/(.*/(HEAD | \
			info/refs | \
			objects/(info/[^/]+ | \
				 [0-9a-f]{2}/[0-9a-f]{38} | \
				 pack/pack-[0-9a-f]{40}\.(pack|idx)) | \
			git-(upload|receive)-pack))$" \
	/usr/libexec/git-core/git-http-backend/$1

ScriptAlias /git/ /var/www/cgi-bin/gitweb.cgi/
----------------------------------------------------------------
+
To serve multiple repositories from different linkgit:gitnamespaces[7] in a
single repository:
+
----------------------------------------------------------------
SetEnvIf Request_URI "^/git/([^/]*)" GIT_NAMESPACE=$1
ScriptAliasMatch ^/git/[^/]*(.*) /usr/libexec/git-core/git-http-backend/storage.git$1
----------------------------------------------------------------
