[WB23] _ Test for page existing (no replies)

Hi All

WB23 - Dynamic site

I want to test if a user has already opened a specific page and if he has then do not reload the page but either (1) switch to that tab or (2) popup a message telling them the page is already open and they should switch to the tab themselves.

Any suggestions? I am aware of PageExists() and PageRefresh() but do not understand how to use these to achieve the desired result as per above.

Thanks
