The 'launch' button in the SPP Web UI is designed to generate a custom URI with an "rdp://" URI scheme.
Browsers use URI scheme handlers to open applications for URI schemes. An example of one such URI scheme is the "file://" scheme. Entering
The browser will download the specified PDF through the browser because that is the behavior defined through a URI scheme handler.
Similarly, the 'launch' button in the SPP Web UI generates a custom URI containing Session connection information with the URI scheme "rdp://".
Currently Microsoft Windows does not have a built-in URI scheme handler to support rdp:// URI schemes.
One Identity has logged an enhancement request with Microsoft to add support for rdp:// URI schemes. One Identity has made similar requests for other RDP solution providers (RoyalTS & FreeRDP) to support URI schemes in a web browser..
SSH sessions use a ssh:// URI scheme. Later versions of WinSCP do install a handler to support ssh:// schemes. Any SSH session initiated from Safeguard’s web interface, will initiate Putty if WinSCP is installed.
A custom handler to launch an application can be configured by changing Microsoft Registry settings. Information on doing this can be found at
