Subject: [PATCH v3] http: document sslcert and sslkey types and extend to proxy

From: "Ricky Davidson via GitGitGadget" <[email-masked]>
Date: Thu, 20 Apr 2023 20:11:40 +0000

From: Ricky Davidson <[email-masked]>

0a01d41ee4 (http: add support for different sslcert and sslkey
types., 2023-03-20) added http.sslCertType and http.sslKeyType, but:

1. it does not document the feature.
2. it does not apply to SSL proxy equivalents.

Documents http.sslCertType and http.sslKeyType. Implements
http.proxySSLCertType. Does the same for http.sslKeyType and
http.proxySSLKeyType equivalents and related environment
variables.
