I have this link to an ibooks file:

 

<a data-role="button" data-icon="arrow-r" data-inline="true" data-mini="true" href=" http://ilitapps.com/u/iLitUserGuideTeacher1_0.ibooks">Teacher User Guide <i>(20-Aug-12)</i></a>

 

.htaccess has this mime type association:

 

AddType application/x-ibooks+zip .ibooks

 

1st tap on the link returns "undefined", then the FQDN URL appears in the Safari iOS browser. clicking refresh with the link in address bar does associate properly and opens in ibooks.

 

Any ideas why the 1st attempt returns "undefined" ?
