Simulate Basic authenfication with cookie

[michael]

Hi all,

I want to do some kind of SSO in my webapps, so I want to put a
Principal in my request. I could do so by generating a cookie, which
contain the simulation of the Basic authentification : "Basic
encodedBase64(userassword)", then the reverse proxy and so on will
fill in the request.

My pb is : the space after "Basic" is transformed in %20 when i create
the cookie.

Does someone simulate basic authentification with cookie ? How could i
fix it ?

Thanks
