If you have the signed certificate for the URL you're developing for,
then yes, you can use the certificate. For example, if your app is going
to app.squid-cache.org and you have the signed certificate for
app.squid-cache.org or *.squid-cache.org, then everything will be happy.
But, if you're trying to intercept the traffic for a third-party domain,
no, you can't. The best you can do, is to create your own CA and add the
public certificate to the browser/application, if it even allows you to.
