Subject: Curl_disconnect: treat all CONNECT_ONLY connections as "dead"
X-Git-Tag: curl-7_65_0~124
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=e06b8bdae6a6e552d7430c00853d18b9378eac29;p=curl

Curl_disconnect: treat all CONNECT_ONLY connections as "dead"

Since the connection has been used by the "outside" we don't know the
state of it anymore and curl should not use it anymore.

Bug: https://curl.haxx.se/mail/lib-2019-04/0052.html

Closes #3795
