This article describes how to automatically pre-populate the domain name in Citrix Web Studio logon page.
Citrix Web Studio
Read/write access to C:\Program Files\Citrix\Web Studio\Site
Navigate to Web Studio → Settings → Authentication
Configure the required domain and authentication settings directly from the interface instead of modifying JavaScript files manually.

On the Web Studio server, navigate to the following directory:
C:\Program Files\Citrix\Web Studio\Site and edit the JavaScript file named: projects_mainapp_src_bootstrap_ts.[hash].js
Examples:
2305: projects_mainapp_src_bootstrap_ts.fd27be00b65d1373.js
2311: projects_mainapp_src_bootstrap_ts.46e9935ed0f6878f.js
Open the file in a text editor and search for the following entries:
this.domain=""
since CVAD 2511:There should be two occurrences of each entry
Update both values with the required domain name.
For example:
this.domain="abc.com"
this._domain="abc.com"
Save the file
Run the iisreset
Log back in to Web Studio.
If the domain name is still not displayed when switching sites, clear the browser cache and validate again.
