Re: SSL client authentication

You can't do that using command line curl, other than the way you mentioned (multiple URLs on command - if it is supported).

You can use the libCurl API to write your own command line tool and do this, if you want. You can re-use the curl handle as many times as you want.

I am accessing a server requiring SSL client authentication.
I am able to login using my client certificate with curl.
The problem is when I do a another invoke of curl.
I have to supply my client certificate with each invoke.
I wish to authenticate the first time only.
How can another invoke of curl be instructed to use the same session as the first invoke so authentication is not needed for each invoke?  I know this behavior is possible because a browser user need only authenticate with the web server once during a session.  Please see curl output below.  As an observation, I noticed supplying multiple URLs on the command line does not require re-authentication.  But I would like to use multiple invokes of curl.
