in reply to Inconsistent errors when trying to establish SSL-connection

$browser->proxy(['http','https'],'http://myproxy:8080');

You are sending https requests via an http proxy. That strikes me as a Very Bad Idea. Why are you using a proxy in the first place?

    It is perfectly normal to proxy HTTPS with a a HTTP proxy. Proxying HTTPS is done by making a CONNECT request to establish a tunnel and the speak the normal TLS inside the tunnel. Thus you have still all the protections offered by TLS. See RFC 2817 section 5 for more details.

      Thanks for the pointer to RFC 2817, which explains a lot. It does still leave me wondering quite what the purpose is of using a proxy in such a situation. It can't be caching because the proxy cannot read the content and it can't be monitoring for the same reason. Any thoughts?

        A proxy is not necessarily a caching proxy. Often proxies are employed at firewalls or similar to enforce policies which sites can be visited and to filter traffic. In these cases use of a proxy is mandatory, i.e. there is no direct way to the internet.

    The proxy is mandatory to access the Internet or our Intranet, because it enforces data policies in my company. It doesn't serve any caching purpose.
