1 I have a private ikiwiki (3.20170111) which is running on a host that serves HTTP and HTTPS, but ikiwiki is configured for (and only served on) HTTPS:
3 url: https://redacted/phd/
4 cgiurl: https://redacted/phd/cgi
6 However, form submissions from ikiwiki are going to a HTTP URL and thus not being served. Example headers from submitting a comment:
10 Request URL:https://redacted/phd/cgi
13 Remote Address:redacted:443
14 Referrer Policy:no-referrer-when-downgrade

30 The CGI is served by lighttpd, but the whole site is front-ended by nginx, which reverse-proxies to lighttpd.
34 I think this might be to do with nginx not rewriting POST URLs when reverse-proxying, but I'm not sure why
35 they would be generated in an HTTP form in any case, except perhaps by lighttpd's CGI handler since the back
36 end is HTTP. A workaround is for nginx to redirect any HTTP URI to the HTTPS equivalent. I initially disabled
37 that so as to have the path for letsencrypt negotiation not redirected.-- [[Users/Jon]]
