7 IkiWiki generates self-referential URLs using the `url` and `cgiurl`
8 configuration parameters, and the `urlto()` and `cgiurl()` functions;
9 the code you quoted isn't involved (it's choosing whether to set
10 HTTPS-only cookies or not, rather than choosing how to generate
11 self-referential URLs).
13 If you want your wiki to be accessible via both HTTP and HTTPS, and use
14 whichever the user first requested, you should set both `url` and
15 `cgiurl` to the same URI scheme and hostname with no port specified,
16 either both `http` or both `https`, for instance:
18     url: http://www.example.com/
19     cgiurl: http://www.example.com/ikiwiki.cgi
21 or
23     url: https://example.org/wiki/
24     cgiurl: https://example.org/cgi-bin/ikiwiki
26 (or the Perl-syntax equivalents if you're not using a YAML
27 setup file).
29 If you use one of those, IkiWiki will attempt to generate
30 path-only links, like \"/wiki/\" and \"/cgi-bin/ikiwiki?...\",
31 whenever it's valid to do so. A visitor using HTTP will stay
32 on HTTP and a visitor using HTTPS will stay on HTTPS.
34 The choice of `http` or `https` for the `url` and `cgiurl`
35 still matters when a URL *must* be absolute, such as in an
36 RSS feed.
38 I improved this code in late 2010 for this todo item:
39 [[todo/want_to_avoid_ikiwiki_using_http_or_https_in_urls_to_allow_serving_both]].
40 It's possible that it has regressed (that's happened
41 a couple of times). If it has, please quote your exact
42 `url` and `cgiurl` configuration.
