  Installing mod_webapp and using it with Apache 1.3
  --------------------------------------------------
  
  Once you have successfully built the mod_webapp DSO as described in the
  README.txt file coming with the sources, installing the module is pretty
  easy.
  
  First of all, copy the resulting mod_webapp.so file you will find in this
  directory into your Apache 1.3 "libexec" directory (that directory where
  all DSO modules for Apache reside).
  
  Once you have done that, edit your "httpd.conf" configuration file and
  add a few lines to load that module at startup:
  
      LoadModule webapp_module libexec/mod_webapp.so
  and
      AddModule mod_webapp.c
  
  Looking at the default "httpd.conf" file coming with Apache 1.3, I usually
  add the "LoadModule ..." line at the end of all pre-written and commented out
  "LoadModule" directives, and my "AddModule ..." directive at the end of all
  commented out "AddModule" directives. My "httpd.conf" file looks something
  like this:
  
      [...]
      #LoadModule unique_id_module  libexec/mod_unique_id.so
      #LoadModule dav_module        libexec/libdav.so
      #LoadModule ssl_module        libexec/libssl.so
      LoadModule webapp_module      libexec/mod_webapp.so
      [...]
      ClearModuleList
      [...]
      #AddModule  mod_unique_id.c
      #AddModule  mod_dav.c
      #AddModule  mod_ssl.c
      AddModule   mod_webapp.c
      [...]
  
  Once you've edited your "httpd.conf" in such fashion, it's better to check
  if everything still works within the Apache core. You can test your newly
  constructed configuration by issuing:
  
      apachectl configtest
  
  The apachectl script comes with your Apache 1.3 distribution. It usually
  lies in /usr/local/apache/bin, but depending on _YOUR_ apache distribution,
  that might change.
  
  Once you verified that "apachectl" reports "Syntax OK" (meaning that all
  modules have been successfully loaded and started), you can start adding your
  web application connections and context into the Apache configurations.
  Back to the "httpd.conf" file, you need to add something like:
  
      WebAppConnection conn      warp  localhost:8008
      WebAppDeploy     examples  conn  /examples
  
  In this example, I'm instructing the WebApp connector to connect to the
  servlet container waiting for requests on the current "localhost" host and
  bound to port 8008 (note, this port is the one you specified in your
  "server.xml" file for the "org.apache.catalina.connectors.warp.WarpConnector"
  connector, not your HTTP one).
  
  A brief detailed description of the above-mentioned directives is:
  
      WebAppConnection [connection name] [provider] [host:port]
  
          [connection name]
              A unique name for the connection to be created between Apache
              and Tomcat.
  
          [provider]
              The name of the provider used to connect to the servlet container.
              Currently only the "warp" provider is available.
  
          [host:port]
              The host name and port number to which the WARP connection must
              attempt to connect. The port is the one you specified in your
              "server.xml" file for the "...WarpConnector" connector, not your
              HTTP one.
  
      WebAppDeploy [application name] [connection name] [url path]
  
          [application name]
              The application name as present in your "webapps" directory in
              Tomcat. For example, if you want to deploy a WAR-based web
              application, your application name will look something like
              "myApplication.war".
  
          [connection name]
              The name of a previously declared WebAppConnection directive.
  
          [url path]
              The URL path where this application will be deployed.
  
  The "WebAppDeploy" directive is scoped around the current host, meaning that
  if you insert it into a "<VirtualHost ...>" tag, your application will be
  deployed only for that particular virtual host. To deploy the same application
  on several virtual hosts, you will have to declare it once inside each
  "<VirtualHost ...>" tag. This, in accordance with the Servlet specification,
  will create a new instance of the web-application per virtual host.
  
  Another directive is available for the WebApp connector. The "WebAppInfo"
  directive will allow you to see the current status of all configured
  connections and deployed applications. To use it, simply add something like:
  
      WebAppInfo /webapp-info
  
  You can then access the information page hitting your web server for the
  following URL:
  
      http://server.name:port/webapp-info/
  
  Have fun...
