Item13925: Leading spaces in DefaultUrlHost causes malformed URL links.

I've setup a wiki to use NatSkin globally in Site preferences. The mail notification is working for users who subscribe to the topics. I'm using a cronjob to push the notification with the following code:

cd /var/www/wiki && /usr/bin/perl -I /var/www/wiki/bin tools/mailnotify -q -nonews

When the user receives the notification, link to the topic is malformed in the HTML message:

<h2>Production // Wiki </h2>
<p>New or changed topics in the Production web, since 12 Jan 2016 - 17:32 GMT:</p>
<ul style="margin:1em 0;padding:0 0 0 1.5em;"><li style="margin:0 0 1em"> <a class='natExternalLink' href="http://myserver/wiki/%3Ca%20href="http://myserver/wiki/Production/MicrosoftOfficeMacros"">http://myserver/wiki/Production/MicrosoftOfficeMacros"</a>>Microsoft Office Macros</a> 
<br />
<a href="http://myserver/wiki/Main/AlexAnder">AlexAnder</a>, 13 Jan 2016 - 09:10
</li>

I've workaround this issue by creating a copy of the original template: templates/mailnotify.nat.tmpl

Original code:

%TMPL:DEF{"HTML:middle"}%<li style="margin:0 0 1em"> <a href="%SCRIPTURL{view}%/%ENCODE{%WEB%}%/%ENCODE{%TOPIC%}%">%GETTOPICTITLE{"%WEB%.%TOPIC%"}%</a>

Temporary fix:

%TMPL:DEF{"HTML:middle"}%<li style="margin:0 0 1em"> %SCRIPTURL{view}%/%ENCODE{%WEB%}%/%ENCODE{%TOPIC%}%

After this change the URL link was sent as:

<ul style="margin:1em 0;padding:0 0 0 1.5em;"><li style="margin:0 0 1em">  <a class='natExternalLink' href="http://myserver/wiki/Production/MicrosoftOfficeMacros">http://myserver/wiki/Production/MicrosoftOfficeMacros</a>

Please check your the settings $Foswiki::cfg{ScriptUrlPath} and $Foswiki::cfg{ScriptUrlPaths}{view} in your LocalSite.cfg. What are their values?

Try disabling $Foswiki::cfg{NatSkin}{DetectExternalLinks}.

As usual you put me on the right direction, the issue is now fixed, but not by disabling: $Foswiki::cfg{NatSkin}{DetectExternalLinks} it was something else.

The values seems to be OK for my setup:

$Foswiki::cfg{ScriptUrlPath} = '/wiki/bin'; $Foswiki::cfg{ScriptUrlPaths}{view} = '/wiki';

I'm always using the web interface to configure the settings. Within my LocalSite.cfg I've found an extra space in my DefaultUrlHost:

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

Strangely when I check the configure web page, there was no visible space one it. In the configure web page I deleted everything in the text box, manually typed the URL of my server and saved the settings. After doing this the settings was saved properly:

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

Now everything works properly, thank you so much!

The configure checker should have been flagging DefaultUrlHost with a warning that "Current setting does not match HTTP_HOST servername". I'll add a check for leading spaces for 2.0.4 / 2.1.
