Description Michal Vyskocil 2009-12-29 10:19:09 UTC

Version:            (using Devel)
Installed from:    Compiled sources

Konqueror refuses to open an URL with an underscore. I tryed to open:
http://vzory_smluv.a4.cz/protokol.html

Konqyeror shows only a meessage box with "Malformed URL
http:/protokol.html" text and refuses to open it. Other applications - Firefox, curl, wget - opens it without a problem.

The a4.cz is accessible, but when I type vzory_smluv.a4.cz (or http://vzory_smluv.a4.cz, or http://foo_bar.com) into adress bar I got the error page

The requested operation could not be completed

I can confirm this.
Qt: 4.6.1
KDE Development Platform: 4.3.85 (KDE 4.3.85 (KDE 4.4 Beta2)) "release 8"
Konqueror: 4.3.85 (KDE 4.3.85 (KDE 4.4 Beta2)) "release 8"

That domain violates STD3. STD3 requires all DNS domain names to be limited to Letters, Digits and Hyphen.

Comment 3 Christoph Bartoschek 2010-01-15 18:24:41 UTC

Is there a reason to not extend the standard? Apparently such domains are used.

Comment 5 Anders Lund 2010-02-13 17:47:56 UTC

Isn't is legal with underscores in the hostname?
In any case, if there is an invalid URL, it would be nice with a meaningful error message :)
