From 511cfd3bffa685fda0e7c25bfa08082aa0de3a30 Mon Sep 17 00:00:00 2001 From: Christian Couder Date: Mon, 16 May 2022 10:38:51 +0200 Subject: http: add custom hostname to IP address resolutions Libcurl has a CURLOPT_RESOLVE easy option that allows the result of hostname resolution in the following format to be passed: [+]HOST:PORT:ADDRESS[,ADDRESS] This way, redirects and everything operating against the HOST+PORT will use the provided ADDRESS(s). The following format is also allowed to stop using hostname resolutions that have already been passed: -HOST:PORT See https://curl.se/libcurl/c/CURLOPT_RESOLVE.html for more details. Let's add a corresponding "http.curloptResolve" config option that takes advantage of CURLOPT_RESOLVE. Each value configured for the "http.curloptResolve" key is passed "as is" to libcurl through CURLOPT_RESOLVE, so it should be in one of the above 2 formats. This keeps the implementation simple and makes us consistent with libcurl's CURLOPT_RESOLVE, and with curl's corresponding `--resolve` command line option. The implementation uses CURLOPT_RESOLVE only in get_active_slot() which is called by all the HTTP request sending functions.
