The RAS Web Portal Setup wizard opens. Read the info on the Welcome page and click Next. On the next page, read the End-User License Agreement. If agreed, select the I accept the terms in the License Agreement option and click Next. On the RAS Web Server Port page, specify the port number. The RAS Secure Client Gateway is installed on port 80 by default and is configured to forward HTTP requests to the local host on port 81. Therefore, clients will still be able to access the RAS Web Portal on port 80. You can choose to install the RAS Web Service on any other port, and also use an existing port used by other web sites. Click Next and then click Install. Click Finish when the installation is completed. Please note that IIS7 caches dynamic content as well as static content. To disable the caching for .aspx, .asmx and .ashx pages for the RAS Web Portal directory with an asp.net page that depends on the session state, perform the following on the RAS Web Server, 2XWebPortal, and 2XWebService. Disabling Caching for folders consisting on .aspx, .asmx and .ashx Run the Server Management console. Navigate to Roles > Web Server (IIS) > Internet Information Services. Repeat steps 4 to 12 for the following sites: RAS Web Server, 2XWebPortal, and 2XWebService. Select the folder that contains the .aspx, .asmx and .ashx pages for which you need to disable caching. In the Feature View, double-click Output Caching. If there is a rule there already for the .aspx extension, double click it and continue from step 8. Otherwise right click and select Add. Enter .aspx for the File name extension. Check User-mode caching. Select Prevent all caching. Check Kernel-mode caching. Select Prevent all caching. Click OK. Close the Server Management Console.
