Configure IIS7 as a proxy with weblogic server.

To configure the WLS proxy, first thing to do is to place the iisproxy.dll, iisforward.dll and iisproxy.ini in the root folder of the website.

 

In this example, I use the Default Website that is installed with IIS. So the above files are copied into its root directory, which is C:Inetpubwwwroot >  (NOTE, for a smooth working of the configuration, always copy the iisforward.dll and iisproxy.dll into the root directory of the WebSite. Otherwise, loading module, iisforward.dll will fail due to permission issues)

 

The iisproxy.ini has the following parameters:

 

WebLogicHost=<dns name or ip addgress>

WebLogicPort=<litening port for WLS>

WlForwardPath=/examplesWebApp

 

WlForward is the web application you want to proxy to in this example, If all web applications are to proxy to WebLogic Server just use WlForwardPath=/

 

Debug=ALL

Optional and used to collect debug information.  It is logged by default in c:TEMPwlproxy.log

DebugConfigInfo=ON

 

DebugConfigInfo is also is only used for debugging, the default is OFF.

Also note the WebLogicCluster=myweblogic.com:7001,yourweblogic.com:7001 line if you are using clusters.  This replaces the WebLogicHost and WeLogicPort entries.

 

(See  http://docs.oracle.com/cd/E23943_01/web.1111/e14395/plugin_params.htm for complete parameter list)

 

So just to get started all that needs to be in the issproxy.ini is the following when proxying is done by the Web Application name, if proxying exclusively by mime type (e.g.; .jsp) WlForwardPath does not need to be specified in the iisproxy.ini

 

NOTE: This is case sensitive

 

WebLogicHost=<dns name or ip address>

WebLogicPort=<listening port for WLS>

WlForwardPath=/examplesWebApp

 

 

This is a sample output from the directory/folder that the iisproxy.dll, iisforward.dll and iisproxy.ini is placed

And here is how it looks from IIS 7.0 (Default Web Site à content View)

Note: I am using the Default Web Site in this example.

 

If you do not have IIS 7.0 installed in your Windows Server 2008, follow the instructions in the below link to install IIS7.0

http://learn.iis.net/page.aspx/29/installing-iis7-on-windows-server-2008/

Now configure IIS 7.0

Before you configure IIS 7.0, make sure IIS 7.0 is installed with ISAPI Filters and ISAPI Extensions. If installed then Default Web Site à Features View should look like below:

 

 

 

 

 

If you do not see the ISAPI Filter icon in the Feature View, go to “Server Manager”, in thee left pane under Roles, click on Web Server (IIS)

Then click on “Add Role Services” on the Right pane.

Then check “ISAPI Filters” and “ISAPI Extensions” and click “Next” and then click on Install

 

 

Now go back to IIS 7.0 and click on Default WebSite as shown below:

Click on ISAPI filters icon in Features View.

In the right pane click on Add

Enter any name of your choice for filter name

Click browse (…) and selects iisforward.dll from C:/inetpub/wwwroot and then ok

 

 

 

 

Next go back to Default Web Site, click on “Handler Mappings”

 

Click on the ‘Add Script Map…’ on the right hand side menu options. Enter * for the Request path. Browse to the iisproxy.dll file and add it as the executable. Name it as  ‘proxy’.

 

 

Click on the Request Restrictions… button and uncheck the box titled ‘Invoke handler only if the request is mapped to’.

 

 

Click Ok to add this Handler mapping. Click ‘Yes’ on the Add Script Map dialog box.

 

Similarly, if you want to configure proxying by path click on Add Script Map and give the Request path as ‘.wlforward’ and select the executable as iisproxy.dll.

Click on the Request Restrictions… button and uncheck the box titled ‘Invoke handler only if the request is mapped to’.

Click Ok to add this Handler mapping. Click ‘Yes’ on the Add Script Map dialog box.

 

Click on the Root node of the IIS Manager tree and click on the ISAPI and CGI Restrictions.

 

Then click on “Edit Feature Settings” on the right hand side menu options

Check the ‘Allow unspecified ISAPI modules’ checkbox and click Ok

 

 

Restart IIS. Go to Default Web site and click on Restart on the right hand side menu.

 

Now access the Example web-application through IIS at http://localhost/examplesWebApp
