Recently, Citrix announced an experimental new feature in Workspace Cloud Labs, the Browser Apps Service
This new service. allows you to easily browser compatibility issues Web applications via a hosted web browser to provide security to solve, increase or improve performance over high latency connections.
So far, Citrix received many positive feedback from our customers has. But still have one question customer is asked the number "If Citrix is able to offer the Browser Apps service as on-premise product?" The answer: We already have. The Browser Apps service runs completely on off-the-shelf Citrix technologies that you can buy today.
In this post I will look Have a look behind the scenes, such as the browser built Apps service and how to deliver it to Citrix a great ease of use for end users for hosted web applications.
is XenApp.
the same XenAppperformed under the covers, the Browser Apps service technology we all know. The Citrix Workspace cloud operations team manages the service the same studio and Director use today use. VDAS created using Machine Creation Services. Web applications are published, publicly available PowerShell SDK.
for the control plane, Citrix chose the hosted applications and desktops to use Service Citrix Workspace cloud. This ensures the Service Evergreen with the latest updates is maintained. and we can use new features such as Azure VDA provision which currently is only available through the apps and desktops service.
Seamless User Experience
One of the main objectives the service is to make as seamless as possible for the end user experience. A workflow of the user should not be changed when a web app should hosted by the Browser Apps service user continues typing in a URL or click a hyperlink, as if they were accessing a normal Web site, without even to be aware of what happens in the browser Apps service behind the scenes. To get this experience, Citrix uses a combination of features of XenApp, storefront, and the web browser itself.
Receiver for HTML5
Citrix Web application would be displayed directly in a tab Web browser of the user, not as a separate window, and did not want the users are prompted to install a client. To achieve this, we use Citrix Receiver for HTML5. This receiver is written entirely in JavaScript and no installation is in any modern web browser, is required. To use it, simply configure a Receiver for Web site, the apps with HTML5 always returns, or the receiver for HTML5 SDK download and host it directly to a web page of their own.
Kiosk mode
The Browser Apps service is designed for the provision of certain web application to end users for not general purpose web browsing. Thus, Citrix decided to hide the fact that we are running a web browser in a different web browser. Web browsers support a special kiosk mode, which does exactly this: it runs a single web application in full-screen mode, without navigation or menu bars.
- Google Chrome: chrome.exe kiosk
- Microsoft Internet Explorer: iexplorer.exe -k
Add links to web pages
The next step is a seamless user experience in providing the app via a launch URL or other web pages via email can be embedded, like any other web application. If use storefront, Receiver for Web has a feature that allows you to create shortcut URLs that go directly to a specific application. The user does not go through the normal process by browsing applications or adding them to your favorites. From Receiver for Web console, just click on the object "links to websites add" to get a URL that you can embed in another intranet site to provide a direct access to this application.
unauthenticated users
[1945003Schließlich] Users of the browser Apps services do not have separate login information. The Web browser will not run on a particular Active Directory user account, so Citrix used the unauthenticated users in XenApp introduced function 7.6. This function creates a pool of local user accounts on each VDA, named Anon000 by Anon999, and users are temporarily on one of these users for the life of their session.The unauthorized user function is assigned to particularly useful when deploying web applications on client on the local intranet, as it can start without login prompt the user. If the delivery groups you create to check simply shown the table below, then create an unauthenticated storefront memory access to these applications to provide.
Configuring policies
In a more secure environment and a good user experience, in addition to just Internet Explorer or Chrome runs as a published app, have many GPOs be adjusted to the VDAS. The list below is not comprehensive, but a published Web browser on a multi-session (Remote Desktop Services) environment.
