Prerequisites:

  1. You must install the required extensions for URL Rewrite and APR in Microsoft IIS.
    Url-Rewrite-Download
    Application-Request-Routing-Download 
  2. This guide assumes you are using Microsoft IIS 7

 

Step 1                                        Creating a Server Certificate


Note: Step 1 only needs to be done if you don't have an SSL cert for your server already.


1. First step is to create a SSL cert for the VisibleThread Doc server via Microsoft IIS
Open your Microsoft IIS server and navigate to the "Server Certificates" node and double click it.

2. In the pane on the right hand side of the window you will see options for creating an SSL cert. For this example I will use a Self-Signed Certifiacte.

You should see the login page of your VT Docs server.

 


Step 4                                      Setting up SSL encryption and port 443


1. To set up SSL encryption and port 443 we just need to add a new binding. Navigate to your Web-Site and you will see in the right pane "Bindings…." Click on this.

2. A window will open and prompt you for information. Where it says "http" this is a drop down click here and select "https". Now specify the I.P of your IIS server and by default port should be set to 443 if not set it to 443. At the bottom of the window there is another drop down menu for you to select which SSL cert you wish to use, select your cert. Now click "ok". Note,if you want public access to your VT Docs application set the I.P as "All Unassigned"

 Preserve Host Headers

Using "Configuration Editor" edit the proxy setting to "Preserve Host Headers"iis1.png

Under the "system.webServer/proxy" change "PerserveHostHeaders" to True iis2.png

 

Increase Request Limit

Some of the URLs created by the application will exceed the character limit of IIS. To resolve this you must increase the limit. You can do this by clicking on "Request Filtering" of your site.iis1.png

 

Next, click on "Edit Feature Settings"iis2.png

Lastly, double the default values to match below. Click OK then restart the site.
