Subject: Lowercase the host name in functions that set it
X-Git-Tag: v_3_0_29~50
X-Git-Url: http://www.privoxy.org/gitweb/?p=privoxy.git;a=commitdiff_plain;h=5981fdcc7bb9ddc21f7d974fdd4336ab0367dbe9

Lowercase the host name in functions that set it

In case of get_destination_from_https_headers() it's important
to get stable hashes for certificates.

In case of get_destination_from_headers() and parse_http_url()
it's mainly cosmetic.
