An Azure service that is used to collect, analyze, and act on telemetry data from Azure and on-premises environments.
@Amol Kankane , Apologies for the delayed response. I tried accessing the page mentioned (bookfish.in) and the returned response does not contain the string "sign". Instead, as the web page is getting loaded through JavaScript, it is getting executed by browser's script engine and elements are being rendered (which are not available for content match).
I verified it using Edge browser and looking at the source ( ctrl+u ). I would suggest using a "string to match" which is contained in the returned HTML page. Hope this helps!
Please let me know if you have any questions.
