- As opposed to existing as a separate process, Citrix Workspace App for HTML5 operates within the frame and process space of the browser itself. As such the browser has the ability to enforce certain security parameters.
- Citrix StoreFront Gateway - HTML5 - No ESP: Handles Citrix Virtual Apps and Desktops traffic including Citrix StoreFront Gateway, HTTP redirect, and Connection Server Listeners (HTML5-8008 and Workspace-Receiver-2598). ESP Engine Disabled. Citrix StoreFront Internal: This template handles internal StoreFront connections. No rewriting of the ICA.
- Applications or published desktops launched with the HTML5 client fail to start. Users see 'Error: Citrix Workspace app cannot launch app' The user may briefly see the 'Connection Interrupted' message displayed immediately at the beginning of the session. Applications or published desktops launched with Citrix Workspace App are successful.
Open a new tab in the Firefox browser.
Type about:config in the address bar.
Double-click network.websocket.allowInsecureFromHTTPS and set the value to true.
Note: This Firefox option might not be supported in Citrix Receiver for HTML5 future versions.
WARNING! This option on Firefox affects the operation of entire Firefox, not just Citrix Receiver for HTML5.
Important Note
As of version 9, Safari browser allows insecure web socket connections. Internet Explorer never allowed non SSL/TLS web socket connections from HTTPS websites. Chrome used to allow it behind a flag, but after the Chrome 44 update, this is no longer supported. Firefox allows it behind a flag (as explained earlier in this article), but it is not recommended. Going forward, only secure (SSL/TLS) web socket connections can be made from Receiver for HTML5.
Problem Cause
When Workspace App for HTML5 is hosted on a https site (default and recommended), non SSL/TLS websocket connections are prohibited by browsers.
In explaining the technical reason behind this it is important to understand the following two principles:
1. As opposed to existing as a separate process, Citrix Workspace App for HTML5 operates within the frame and process space of the browser itself. As such the browser has the ability to enforce certain security parameters.
2. Additionally, when any Workspace App for Windows makes a connection to a VDA for either a published desktop or app, the underlying connection is made to the VDA and not the Storefront server as any kind of intermediate proxy.
This second point is less obvious in the case of Citrix Workspace App for HTML5 because the published desktop or application displays within the browser frame and “appears” to be connected via the Storefront server. Despite this appearance though, the underlying TCP/UDP connection is still between the client and the VDA. If the Storefront base URL is SSL enabled (where it begins with https as is best practice) and the VDA is not SSL enabled (which it is not by default) the browser in this case will prevent the connection due to what it sees as an underlying inconsistency. The inconsistency is that while the URL shown in the browser frame is prefixed with https, the actual underlying connection is not https even though it is not obvious to the user.
There are two solutions for this.
Solution 1 is to enable SSL on the VDA using the following guide:
This will ensure that the connection path is SSL enabled between the internal client and the VDA.
Solution 2 is to have your connections from the clients first go through a Citrix Gateway. Citrix Gateway will proxy the connections and perform a SSL handshake between the client and the Citrix Gateway. In this scenario there is no inconsistency and connections via HTML5 Receiver will succeed.
