Item2288: Broken redirect from Login back to an Edit screen

Version; This site is running Foswiki version Foswiki-1.0.7, Sun, 20 Sep 2009, build 5061, Plugin API version 2.0

Without credentials; http://localhost/foswiki/bin/view/System/WebHome Edit button leads to http://localhost/foswiki/bin/login/System/WebHome?t=1256423029;origurl=//foswiki/bin/edit/System/WebHome%3ft%3d1256423029

Finish login and the page goes to http://www20.search.rogers.com/search?qg=www.foswiki.ca%2Fbin%2Fedit%2FSystem%2FWebHome%3Ffoswiki_redirect_cache%3Daa05580b4d7502d61730e6f49a1f8dad&rn=Pn7Yv26uhNf_dJ2&rg= which is a sneaky ISP redirect, but it still means the Login redirect fails somewhere.

This could well be a local configuration problem?

With Opera setup to block the Roger's sneaky git moves, (which could still influence this, the www.*.ca thing) http://www.foswiki.ca/bin/edit/System/WebHome?foswiki_redirect_cache=18b66e39b6dcf5935872de312db0a2de

Solved, well the symptoms at least LocalSite.cfg had

$Foswiki::cfg{DefaultUrlHost} = 'http://localhost/';

The trailing slash is a no no it seems.

$Foswiki::cfg{DefaultUrlHost} = 'http://localhost';

Deleted the cfg attachment from the task.

Does this require some defensive code around trailing characters for that config option?

-- BrianTiffin - 25 Oct 2009

quite interesting. //bin/view seems to get interpreted as a http:// url with the protocol part missing, so the first portion of the relative URL is mis-interpreted as a hostname.

I've reproduced the effect, but not the cause - so I wonder if you have got some kind of rewrite or redirect rules in your apache config that are adding to the issue.

adding a trailing / to my DefaultUrlHost didn't produce this issue for me - so its got to be caused by more than just that.

I can make a configure checker to warn if there's a trailing slash on {DefaultUrlHost}, would that be enough to close this task?

Yes, though I'd really like to understand why it happens.

Item2597 is a duplicate of this task.

I believe that this has been resolved along the way. The origurl= query param is no longer passed. Setting to No Action.
