1 The edit page CGI defines a `base` tag with an URL which is not
2 absolute, which can break the preview function in some circumstances
3 (with e.g. images not showing). The trivial [[patch]] that fixes
4 it can be found [[here|http://sprunge.us/EPHT]] as well as on [[my
5 git|http://git.oblomov.eu/ikiwiki]].
7 > That patch does mean that if you're accessing the CGI via HTTPS but your
8 > $config{url} and $config{cgiurl} are HTTP, you'll get preview images loaded
9 > via HTTP, causing the browser to complain. See

31 Update: This bug is worse than it first appeared, and does not only affect
32 previewing. The cgi always has a `<base>` url, and it's always relative,
33 and that can break various links etc. For example, when the 404 plugin
34 displays a missing page, it has a Recentchanges link, which would be broken
35 if the cgi was in an unusual place.
37 `misctemplate` needs to *always* set an absolute baseurl. Which is a problem,
38 since `misctemplate` is not currently passed a cgi object from which to
39 construct one. --[[Joey]]
41 Update: Worse and worse. `baseurl(undef)` can be a relative url, but
42 nearly every use of it I can find actually needs to be absolute.
43 the numerous `redirect($q, baseurl(undef))` all need to be absolute
44 according to `CGI` documentation.
46 So, I'm seriously thinking about reverting the part of
47 [[todo/want_to_avoid_ikiwiki_using_http_or_https_in_urls_to_allow_serving_both]]
48 that made `baseurl(undef)` relative.
49 And I suppose, re-opening that todo. :( --[[Joey]]
