Hello everyone,
I wrote a window application that send a document via https. It
creates a HttpWebRequest object and add a certificate to the
ClientCertificates collection. The certificate is taken from the Local
Computer store (through an external library).
The fact is: if the certificate is not installed in the Current User
store, the server returns error 403, Access forbidden. But I took the
certificate from Local Computer store (and it is succefully added to
ClientCertificates collection). Could anyone explain me this (maybe
normal) behavior, please?

Thank all, Gionni
