View source for Setting up IIS as Reverse Proxy for QPR UI

Follow these instructions to route QPR UI http/https traffic though IIS, i.e. setting up IIS to work as a reverse proxy. It has the following advantages:
* Access QPR UI using more standard ports (usually 80 or 443) instead of GlassFish ports (usually 8080 or 8181).
* QPR UI can use HTTPS connection that is configured in IIS, and then there is not need to configure https in GlassFish.
* External presentation objects and embedded QPR Portal works better as the browser considers they are from the same site because same origin policy won't cause restrictions (more information: https://en.wikipedia.org/wiki/Same-origin_policy)

== Instructions ==

1. Download and run '''Microsoft Web Platform Installer''' (available in http://www.microsoft.com/web/downloads/platform.aspx). Use it to install '''URL Rewrite 2.1''' (or newer) and '''Application Request Routing 3.0''' (or newer) modules. Use the search box to find these components. If you had the IIS Manager open while installing the components, restart the IIS Manager.

2. Create file '''C:\inetpub\wwwroot\EnticeServices\web.config''' with following contents (also create the '''EnticeServices''' folder):
<pre>
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <system.webServer>
  <rewrite>
    <rules>
      <rule name="Reverse Proxy to EnticeServices" stopProcessing="true">
        <match url="(.*)" />
        <action type="Rewrite" url="http://localhost:8080/EnticeServices/{R:1}" />
	<serverVariables>
          <set name="HTTP_X_ORIGINAL_ACCEPT_ENCODING" value="{HTTP_ACCEPT_ENCODING}" />
          <set name="HTTP_ACCEPT_ENCODING" value="" />
        </serverVariables>
      </rule>
    </rules>
    <outboundRules>
      <rule name="Change port">
        <match filterByTags="A, Form, Img" pattern="^http://localhost:8080/(.*)" />
        <action type="Rewrite" value="http://localhost/{R:1}" />
      </rule>
    </outboundRules>
  </rewrite>
  </system.webServer>
</configuration>
</pre>

3. Create file '''C:\inetpub\wwwroot\ui\web.config''' with following contents (also create the '''ui''' folder):

<pre>
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <system.webServer>
  <rewrite>
    <rules>
      <rule name="Reverse Proxy to QPR UI" stopProcessing="true">
        <match url="(.*)" />
        <action type="Rewrite" url="http://localhost:8080/ui/{R:1}" />
	<serverVariables>
          <set name="HTTP_X_ORIGINAL_ACCEPT_ENCODING" value="{HTTP_ACCEPT_ENCODING}" />
          <set name="HTTP_ACCEPT_ENCODING" value="" />
        </serverVariables>
      </rule>
    </rules>
    <outboundRules>
      <rule name="Change port">
        <match filterByTags="A, Form, Img" pattern="^http://localhost:8080/(.*)" />
        <action type="Rewrite" value="http://localhost/{R:1}" />
      </rule>
    </outboundRules>
  </rewrite>
  </system.webServer>
</configuration>
</pre>

4. Open '''Internet Information Services (IIS) Console''', click the top level in the left side hierarchy, doubleclick '''Application Requests Routing Cache''', click '''Server Proxy settings''' on the right pane, click '''Enable Proxy''' and click '''Apply'''.

5. In '''Internet Information Services (IIS) Console''', click '''EnticeServices''' folder in the left side hierarchy and double-click '''URL Rewrite'''.

6. Click '''View Server Variables...''', and add '''HTTP_X_ORIGINAL_ACCEPT_ENCODING''' and '''HTTP_ACCEPT_ENCODING''' using the '''Add''' button.

7. Do the steps 5. and 6. also for the '''ui''' folder.

8. QPR UI can now be accessed using url '''http(s)://SERVER/ui/''' where SERVER is the hostname of the server.
