<div class="paragraph"><p>Make sure that you have HTTP support, i.e. your Git was built with
libcurl (version more recent than 7.10). The command <em>git http-push</em> with
no argument should display a usage message.</p></div>
<div class="paragraph"><p>Then, add the following to your $HOME/.netrc (you can do without, but will be
asked to input your password a <em>lot</em> of times):</p></div>
<div class="literalblock">
<div class="content">
<pre><code>machine &lt;servername&gt;

<div class="paragraph"><p>If you want to access the web-server by its IP, you have to type that in,

<div class="content">
<pre><code>curl --netrc --location -v http://&lt;username&gt;@&lt;servername&gt;/my-new-repo.git/HEAD</code></pre>

the content of the file HEAD on the server.</p></div>

you want to export:</p></div>

<div class="paragraph"><p>It is important to put the last <em>/</em>; Without it, the server will send
a redirect which git-http-push does not (yet) understand, and git-http-push
will repeat the request infinitely.</p></div>

<div class="literalblock">
<div class="content">
<pre><code>Error: no DAV locking support on remote repo http://...</code></pre>
</div></div>
<div class="paragraph"><p>then it means the web-server did not accept your authentication. Make sure
that the user name and password matches in httpd.conf, .netrc and the URL
you are uploading to.</p></div>
<div class="paragraph"><p>If git-http-push shows you an error (22/502) when trying to MOVE a blob,
it means that your web-server somehow does not recognize its name in the
request; This can happen when you start Apache, but then disable the
network interface. A simple restart of Apache helps.</p></div>
<div class="paragraph"><p>Errors like (22/502) are of format (curl error code/http error
code). So (22/404) means something like <em>not found</em> at the server.</p></div>
<div class="paragraph"><p>Reading /usr/local/apache2/logs/error_log is often helpful.</p></div>

<div class="content">

<div class="paragraph"><p>If you access HTTPS locations, Git may fail verifying the SSL
certificate (this is return code 60). Setting http.sslVerify=false can
help diagnosing the problem, but removes security checks.</p></div>
