I have below scenario
- www.site1.com is opened in one browser window/tab (Which is my website)
- www.customersite.com, opened in another browser which is client website.
I have full control over site1.com and I can give a script to embed in the www.customersite.com.
I wanted to inform www.customersite.com whenever www.site1.com is opened in another window. And when www.customersite.com gets to know that www.site1.com is opened, it will transmit some data to mysite1 server
I tried https://github.com/pubkey/broadcast-channel but it is only working when both the window are from same origin.
Is there a any way i can achieve this communication? Is there a way to identify site1.com is opened in another window?
If this is not possible is there amy other way to achieve the same?
