KB18241 - Pulse Connect Secure CTS client does not launch when the PCS URL is in IE trusted sites

« Go Back

Information

 
Last Modified Date11/23/2015 7:57 PM
Synopsis
Citrix applications fail to launch using the Pulse Connect Secure Citrix Terminal Services (CTS) client.
Problem or Goal
Clicking on Citrix applications through Citrix Web Interface (WI) results in an error message that the server cannot be found using the Pulse Connect Secure CTS client:
  • If the PCS (and/or Citrix) server/URL is removed from IE trusted sites, the failure does not occur.
  • If Firefox is used, the issue does not occur.
  • If SAM is used, the issue does not occur.
Cause
Solution
If possible, the PCS and Citrix servers should be removed from IE trusted sites; if this is not possible, the following filter needs to be installed to the PCS Appliance.

To install the filter:
  1. Go to Users > Resource Policies > Web > Selective Rewriting
  2. Select Rewriting Filters (installed by default on 6.4 and later PCS OS; pre-6.4 PCS OS versions need a license available from GEC; refer KB10195 for more information). 
     
    If you do not see this option, enable it by clicking on the "customize." button on the far right of the web resource policies page; choose "rewriting filters" and refresh the page.
    The filter to install is filter60350.pkg.encrypted (right-click to save)
  3. Enter the appropriate URL(s)

    Note: You need a '*' at the end of the URL to ensure the policy applies and users are able to launch the Pulse Connect Secure Citrix Proxy application.

    • When using Citrix WI 5.3 and later (only) the filter URL will need to be: *:*/*appembed.aspx?CTX_Application=*
    • When using Citrix WI versions prior to 5.3 (only) the filter URL will need to be: *:*/*appembed.aspx?NFuse_Application=* (please note this is the default filter entry; it will need to be modified for the newer syntax in WI 5.3)
    • When using mixed mode (WI versions 5.3 and WI versions prior to 5.3) please include BOTH resource URLs to allow the launch of the CTS client from either server 

To enable the rewriting filters:
  1. Go to Resource Policies > Access > Web ACL. 
  2. Select the "All Pages
  3. Click OK



For Storefront 2.4/2.5 where Applications are configured to launch via CTS,the filter to install is filter342198.pkg.encrypted

The default URL in the filter will be *:*/Citrix/POBWeb/scripts/Default.htm.script.min.js as below :

We will need to modify the filter URL accordingly based on the URL used in the customer environment,we can use http://www.httpwatch.com basic edition to get the exact URL by accessing the URL directly in LAN and taking a http watch .hwl log.

For example,we need to modify URLs in rewrite filter to *:*/Citrix/MyWeb/scripts/Default.htm.script.min.js or *:*/Citrix/MyWeb/scripts/*.js

For Storefront 3.0/3.1,where Applications are configured to launch via CTS,the filter to install is filter339085.pkg.encrypted

The default URL in the filter will be *:*/Citrix/PRMCStoreWeb/receiver/js/*.js as below :

User-added image

We will need to modify the filter URL accordingly based on the URL used in the customer environment.

For example, we need to modify the URLs to *:*/Citrix/MyStoreWeb/receiver/js/*.js

Note : MyWeb and MyStoreWeb directories above are just examples, we need to input the directory name based on what is configured in the customer's environment.
