To enable anonymous read access but authenticated write access,
-require authorization with a LocationMatch directive:
+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$">
# ...and set up auth.backend here
----------------------------------------------------------------
+
-Note that unlike the similar setup with Apache, we can easily match the
-query string for receive-pack, catching the initial request from the
-client. This means that the server administrator does not have to worry
-about configuring `http.receivepack` for the repositories (the default
-value, which enables it only in the case of authentication, is
-sufficient).

To require authentication for both reads and writes:

----------------------------------------------------------------
All CGI environment variables are available to each of the hooks
invoked by the 'git-receive-pack'.
