 Hi,
 I am looking for a way to intercept a stream before it gets to my
 browser, so I can see everything that is being sent to me, and that I
 send back. Does anyone know know of a tool that will do this for me?
 Cheers
 Antoine

btw, it is in https, but seeing as it is my browser I want to spy on,
isn't that OK?

technically, it is not. You could intercept network traffic at the link
level and even simulate the remote host and its correct address but
you'd need to gain the key and cert of the remote server to make your
solution fully transparent. Usually, you don't have the key.

If it's not intended to be fully transparent, it's no problem to use
any custom certificate for that or even do https only from proxy to
remote server and use plain http to the proxy. Simple network sniffers
won't work here, the traffic would be encrypted.

Seems that ssldump can do the fully transparent decryption of ssl
connections. For the proxy-solution with a new certificate have a look
at the famous dsniff package and read about webmitm. This will be
of interest:
