 +| FileVPathPrefix          | ""               | Virtual path for HTTP file base access, suggested value: ''/files/'' |
 +| FileVPathForVHosts       | ''false''        | If you'd like your virtual hosts to provide HTTP access to your file bases (using virtual file paths), set this to ''true'' |
 +| OutbufDrainTimeout       | ''10''           | Number of milliseconds to wait for output buffer to drain |
 +| TempDirectory            | ''../temp/''     | Override default temporary file directory |
 +| Options                  |                  | See below for details |
 +
 +=== Options ===
 +
 +The ''Options'' key is set to a ''|'' separated list of options to enable.  
 +
 +Default value: **''NO_HOST_LOOKUP | HTTP_LOGGING | NO_CGI''**
 +
 +In addition to the [[config:sbbs.ini|standard options]], the web server also supports the following:
 +
 +== DEBUG_RX ==
 +
 +Log all received data to the console log, as well as various
 +extra bits related to receiving data.
 +
 +== DEBUG_TX ==
 +
 +Log all transmitted data except the reply body itself, as well
 +as various extra bits of information related to transmitted
 +data.
 +
 +== DEBUG_SSJS ==
 +
 +Log server-side JavaScript execution details.
 +
 +== VIRTUAL_HOSTS ==
 +
 +Supports name-based virtual hosts.  If your system has multiple
 +host names, you can have each host name return unique content
 +depending on which hostname is used.  ie: if
 +''freebsd.synchro.net'' and ''nix.synchro.net'' both resolved to your
 +system, you could have FreeBSD-specific pages on one, and 
 +general *nix stuff on the other.
 +
 +A virtual host is added by simply putting the desired content
 +into a sub-directory of [[#RootDirectory]] with the desired hostname
 +ie: ''web/root/freebsd.synchro.net/'' if the browser doesn't send
 +the request host name (very old browsers, or some automated
 +tools) they will be served out of document root.
 +It is therefore a good idea to put links to your various
 +virtual hosts in an ''index.html'' page in [[#RootDirectory]] something
 +like this:
 +<code html>
 +<html>
 +  <head>
 +    <title>Old Browser</title>
 +  </head>
 +  <body>
 +    Your browser is either too old to support
 +    name-based virtual hosts, or you have visited a
 +    virtual hosts that is not yet configured.  The
 +    following are hosted here:<br>
 +    <a href="freebsd.synchro.net">freebsd.synchro.net</a><br>
 +    <a href="nix.synchro.net">nix.synchro.net</a><br>
 +  </body>
 +</html>
 +</code>
 +
 +== NO_CGI ==
 +
 +Disable CGI/FastCGI script execution.
 +
 +== HTTP_LOGGING ==
 +
 +Enable logging to a Common Logfile Format log as described in
 +the HttpLogFile section.  Usefull for running log analysis
 +programs (like Webalizer: http://www.mrunix.net/webalizer/)
 +
 +== NO_JAVASCRIPT ==
 +
 +Disable SSJS execution.
 +
 +== ALLOW_TLS ==
 +
 +Enable TLS/SSL support.
 +
 +== HSTS_SAFE ==
 +
 +Indicates that all URLs available via http are also available via https and redirects clients who want a TLS session to the https location.
