How to clear the cache of the WebBrowser

[Guest]

I use a WebBrowser in a windows form (without connection).
I feed the "DocumentText" property and the result is ok.
But when I try to change the content of my WebBrowser, the original content
appears because it stays in cache. I tried with a TextBox and it's ok)
How can I clear the cache in this case?
Thank you for helping

I found the solution:
the 'AllowNavigation' property must be set to true
