Setting a name that isn't a built-in alternative, will make curl +stay with the default. +.IP "QLOGDIR " +If curl was built with HTTP/3 support, setting this environment variable to a +local directory will make curl produce qlogs in that directory, using file +names named after the destination connection id (in hex). Do note that these +files can become rather large. Works with both QUIC backends. +.IP "SSLKEYLOGFILE " +If you set this environment variable to a file name, curl will store TLS +secrets from its connections in that file when invoked to enable you to +analyze the TLS traffic in real time using network analyzing tools such as +Wireshark. This works with the following TLS backends: OpenSSL, libressl, +BoringSSL, GnuTLS, NSS and wolfSSL. .SH "PROXY PROTOCOL PREFIXES" Since curl version 7.21.7, the proxy string may be specified with a protocol:// prefix to specify alternative proxy protocols. -- cgit v1.2.3
