Can the 'Security Alert' dialog box be captured when recording against a secure Website (HTTPS)?
No, the 'Security Alert' dialog will not be recorded. The dialog is a client side message and is displayed by the browser. It is not received from the server. As Silk Performer records the traffic between the browser and server the dialog is not relevant to the load test and so will not be recorded.
The dialog box will also not be seen in the Truelog Explorer. This is because the TrueLog Explorer is a log of the traffic recorded between the client and the server. As the Security Dialog is only displayed client side it will not be recorded in the TrueLog.
