You could use NoCacheHeaders to force a server call on refresh. Or you could use a POST on the previous page to force a resubmission (which might be a hack depending on why you want to go to the server.)
I tried to apply nocacheheaders in my response but on clicking browser back im getting page expired error and so we tried to implement the 302 redirect and on clicking browser back server call has to be made. please share me the sample code base for the same and how to do a POST on previous page to force a resubmmision.
