Back & Forward buttons

Back & Forward buttons

Hi Everyone,

I've a question on the Browser "Back" & "Front" button

Description:

I'm making an Ajax call and on success i'm updating the query string using pushstate

- Before Ajax call the url is like this for eg:

http://abc.com?params1=abc

- After the Ajax call, the query string is updated as follows using "pushstate"
http://abc.com?params1=def

- Now when the user hits on "Back" button, its not doing anything. It remains as it is.
I wanted to reload the page with the previous history state whihc is

http://abc.com?params1=abc

Can you please recommend the best approach? Appreciate all your time and help!

Thanks & Regards,
Sathya
