1 For security reasons, one of the sites I'm in charge of uses a Reverse Proxy to grab the content from another machine behind our firewall.
2 Let's call the out-facing machine Alfred and the one behind the firewall Betty.
4 For the static pages, everything is fine. However, when trying to use the search, all the links break.
5 This is because, when Alfred passes the search query on to Betty, the search result has a "base" tag which points to Betty, and all the links to the "found" pages are relative.
8 <base href="Betty.example.com"/>
10 <a href="./path/to/found/page/">path/to/found/page</a>
12 This breaks things for anyone on Alfred, because Betty is behind a firewall and they can't get there.
14 What would be better is if it were possible to have a "base" which didn't reference the hostname, and for the "found" links not to be relative.
19 <a href="/path/to/found/page/">path/to/found/page</a>
21 The workaround I've come up with is this.
23 1. Set the "url" in the config to ' ' (a single space). It can't be empty because too many things complain if it is.
24 2. Patch the search plugin so that it saves an absolute URL rather than a relative one.

42 It works for me, but it has the odd side-effect of prefixing links with a space. Fortunately that doesn't seem to break browsers.
43 And I'm sure someone else could come up with something better and more general.

55 >> I did try setting `url` to the "Alfred" machine, but that doesn't seem clean to me at all, since it forces someone to go to Alfred when they started off on Betty.
56 >> Even worse, it prevents me from setting up a test environment on, say, Cassandra, because as soon as one tries to search, one goes to Alfred, then Betty, and not back to Cassandra at all.
57 >> Hardcoded solutions make me nervous.
59 >> I suppose what I would like would be to not need to use a `<base href>` in searching at all.
