Copy and paste in RDS Proxy web applications
Allow or refuse copy and paste between the workstation and a web application, per policy and per direction.
Copy and paste between the workstation and a web application goes through the Remote Desktop clipboard.
Each direction is a right of the policy.
Both rights are off by default.
| Right | Effect |
|---|---|
| Paste into web applications | The user pastes text from the workstation into the page. |
| Copy from web applications | Text copied in the page reaches the clipboard of the workstation. |
These two rights apply to web targets only.
They do not depend on the clipboard rights of RDP targets.
A policy can allow the clipboard on Windows servers and refuse it in web applications, or the other way round.
Set the rights in the policy
Open the policy in Policies.
The section Web applications: clipboard holds the two switches, above the RDP session rights.
The web clipboard rights are separate from the RDP session rights.
Set the rights from the target
The window of a web target has a Copy and paste section.
It lists every policy that gives access to this application, with its two switches.
A click changes the policy at once.
Two policies give access to Artica Accounting.
Only Web applications allows copy and paste.
The rights belong to the policy.
A change made from a target applies to every web application of that policy.
The column Targets of the policy shows how many targets share it.
What the user does
| To | Do |
|---|---|
| Paste into the page | Copy the text on the workstation, click in the field, press Ctrl+V or Shift+Insert. |
| Copy from the page | Select the text in the page and press Ctrl+C. Paste it on the workstation as usual. |
The text copied on the workstation is typed into the field of the page.
The bastion asks the workstation for its text only at the moment of the paste.
Nothing is kept between two pastes, because the text can be a password.
When the right is off, Ctrl+V reaches the page as a normal key and nothing is pasted.
Traces
Each paste writes the event web_paste and each copy writes web_copy.
The event holds the number of characters, never the text.
Limits
- Text only.
Files and images are not transferred. - The paste item of the right-click menu of the page does nothing: the browser of the bastion has no clipboard of its own.
- A paste longer than 1 MB is refused whole.
A copy longer than 4 MB is not offered to the workstation. - The feature needs the RDS Proxy engine 12.3.24 and the authenticator 1.8.1.
With older versions, the console shows a warning and the switches have no effect yet.
