HTTPS and Certificate

[Chris]

Hello.
I have an ASP .NET Application that I have been using
that calls a web service on another machine.

Our company wants to implement HTTPS between the two
applications. I have changed the call to the web service
URL to https://example:8700/example. Now I get a message
indicating:

The underlying connection was closed: Could not establish
trust relationship with remote server.

Does anyone know what I need to do to implement HTTPS? I
have installed the certificate through my browser in a
trusted folder but I can't get my development environment
(Visual Studio) to work. A piece of example code would be
great.

I have seen the same error on many other posts but didn't
see a resolution. Thanks for your help.

Could it be a problem with the certificate name not matching the URL and the
cert policy causing the failure? I've seen lots of weird cert policy
problems cause failures in the underlying webrequest object that the client
proxy uses.

To combat this, you can create your own ICertificatePolicy class and add it
to the ServicePointManager CertificatePolicy property. I usually have the
CheckValidationResult return true for all cases to start with and then go
from there.

If that fixes the problem, then you know it was a certificate trust issue
that caused the failure.

HTH,

Joe K.

As a start point, you may try to visit your new service
https://example:8700/example using IE, you will see a few dialog boxes
poping up which will provide information on exactly what is not accepted by
your computer.
