How to refuse to operate if an invalid certificate is received ?

[Andre Rodrigues <acastanheira2001 () yahoo com br>]

Hi,

We have some app´s that use digital certificate. But, even though the browser says the cert is invalid, the user can 
continue and use the app.

How to configure the app, or the web server, to operate ONLY with a valid cert? 

 Obrigado,
André
