<p>This module <em>requires</em> the service of <code class="module"><a href="../mod/mod_proxy.html">mod_proxy</a></code>. It provides the features used for
    proxying HTTP and HTTPS requests. <code class="module"><a href="../mod/mod_proxy_http.html">mod_proxy_http</a></code>
    supports HTTP/0.9, HTTP/1.0 and HTTP/1.1. It does <em>not</em>
    provide any caching abilities. If you want to set up a caching
    proxy, you might want to use the additional service of the
    <code class="module"><a href="../mod/mod_cache.html">mod_cache</a></code> module.</p>

<p>Thus, in order to get the ability of handling HTTP proxy requests,
    <code class="module"><a href="../mod/mod_proxy.html">mod_proxy</a></code> and <code class="module"><a href="../mod/mod_proxy_http.html">mod_proxy_http</a></code>
    have to be present in the server.</p>

<div class="warning"><h3>Warning</h3>
      <p>Do not enable proxying until you have <a href="mod_proxy.html#access">secured your server</a>. Open proxy
      servers are dangerous both to your network and to the Internet at
      large.</p>

<h2 id="env">Environment Variables <a title="Permanent link" href="#env" class="permalink">&para;</a></h2>
    <p>In addition to the configuration directives that control the
    behavior of <code class="module"><a href="../mod/mod_proxy.html">mod_proxy</a></code>, there are a number of
    <dfn>environment variables</dfn> that control the HTTP protocol
    provider. Environment variables below that don't specify specific values
    are enabled when set to any value.</p>
    <dl>
        <dt>proxy-sendextracrlf</dt>
        <dd>Causes proxy to send an extra CR-LF newline on the end of a
        request.  This is a workaround for a bug in some browsers.</dd>
        <dt>force-proxy-request-1.0</dt>
        <dd>Forces the proxy to send requests to the backend as HTTP/1.0
        and disables HTTP/1.1 features.</dd>
        <dt>proxy-nokeepalive</dt>
        <dd>Forces the proxy to close the backend connection after
        each request.</dd>
        <dt>proxy-chain-auth</dt>
        <dd>If the proxy requires authentication, it will read and
        consume the proxy authentication credentials sent by the client.
        With <var>proxy-chain-auth</var> it will <em>also</em> forward
        the credentials to the next proxy in the chain.  This may
        be necessary if you have a chain of proxies that share
        authentication information.  <strong>Security Warning:</strong>
        Do not set this unless you know you need it, as it forwards
        sensitive information!</dd>
        <dt>proxy-sendcl</dt>
        <dd>HTTP/1.0 required all HTTP requests that include a body
        (e.g. POST requests) to include a <var>Content-Length</var>
        header.  This environment variable forces the Apache proxy to
        send this header to the backend server, regardless of what the
        Client sent to the proxy.  It ensures compatibility when
        proxying for an HTTP/1.0 or unknown backend.  However, it
        may require the entire request to be buffered by the proxy,
        so it becomes very inefficient for large requests.</dd>
        <dt>proxy-sendchunks or proxy-sendchunked</dt>
        <dd>This is the opposite of <var>proxy-sendcl</var>.  It allows
        request bodies to be sent to the backend using chunked transfer
        encoding.  This allows the request to be efficiently streamed,
        but requires that the backend server supports HTTP/1.1.</dd>
        <dt>proxy-interim-response</dt>
        <dd>This variable takes values <code>RFC</code> (the default) or
        <code>Suppress</code>.  Earlier httpd versions would suppress
        HTTP interim (1xx) responses sent from the backend.  This is
        technically a violation of the HTTP protocol.  In practice,
        if a backend sends an interim response, it may itself be
        extending the protocol in a manner we know nothing about,
        or just broken.  So this is now configurable: set
        <code>proxy-interim-response RFC</code> to be fully protocol
        compliant, or <code>proxy-interim-response Suppress</code>
        to suppress interim responses.</dd>
        <dt>proxy-initial-not-pooled</dt>
        <dd>If this variable is set, no pooled connection will be reused
        if the client request is the initial request on the frontend connection. This avoids
        the "proxy: error reading status line from remote server" error message
        caused by the race condition that the backend server closed the
        pooled connection after the connection check by the proxy and
        before data sent by the proxy reached the backend. It has to be
        kept in mind that setting this variable downgrades performance,
        especially with HTTP/1.0 clients.
