I have a html page which generates data into a graph using PHP. The problem I have is that the web browser stores the history of the page.
This is a problem because I redirect my page to a second page every 5 mins. I use this method to alternate between two screens and also because my data is updated real-time.
<meta http-equiv="refresh" content="300; url=myurl.html">
The issue being that after a number of refreshes, the history is saved and the updated information is no longer updated. It just keeps showing the two pages with old info.
How can I force these two pages to flush their history / browsing data?
