Follow up to r1880368 and r1880980:
Complete move to .en.utf8 suffixes in two steps:
1. From fresh checkout, renamed all existing files:
$ for f in *.html.en */*.html.en; do svn mv $f $f.utf8; done
2. Ran "./build.sh all" which also regenerates the typemaps.

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. + </dd> + </dl> +</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div> +<div class="section"> +<h2><a name="notes" id="notes">Request notes</a> <a title="Permanent link" href="#notes" class="permalink">¶</a></h2> + <p><code class="module"><a href="../mod/mod_proxy_http.html">mod_proxy_http</a></code> creates the following request notes for + logging using the <code>%{VARNAME}n</code> format in + <code class="directive"><a href="../mod/mod_log_config.html#logformat">LogFormat</a></code> or + <code class="directive"><a href="../mod/core.html#errorlogformat">ErrorLogFormat</a></code>: + </p> + <dl> + <dt>proxy-source-port</dt> + <dd>The local port used for the connection to the backend server.</dd> + <dt>proxy-status</dt> + <dd>The HTTP status received from the backend server.</dd> + </dl> +</div> +</div> +<div class="bottomlang"> +<p><span>Available Languages: </span><a href="../en/mod/mod_proxy_http.html" title="English"> en </a> | +<a href="../fr/mod/mod_proxy_http.html" hreflang="fr" rel="alternate" title="Français"> fr </a></p> +</div><div class="top"><a href="#page-header"><img src="../images/up.gif" alt="top" /></a></div><div class="section"><h2><a id="comments_section" name="comments_section">Comments</a></h2><div class="warning"><strong>Notice:</strong><br />This is not a Q&A section.
