trouble with external links

Today I tried to set up an "external link" like this:

curl --basic --user 'steinb' -X BIND -H 'Content-Type: text/xml;charset="UTF-8"' --url 'https://www.ibr.cs.tu-bs.de/davical/caldav.php/steinb/' -d '<?xml version="1.0" encoding="utf-8"?><bind xmlns="DAV:"><segment>Schulferien 11-12</segment><href>http://www.sunbird-kalender.de/extension/kalender/Schulferien_2011-2012_NI.ics</href></bind>'

This request always gave an "<bind-source-exists/>The BIND Request MUST identify an existing resource." error. After modifying the if-clause in caldav-BIND.php around line 51 that differentiates internal from external hrefs to just

if ( preg_match ( '{^https?://[A-Za-z][^/]*/.+$}', $href ) ) {

it seems to work as expected.

Hi Andrew,

after a period of inactivity on this issue, today I tried again to use BIND for external calendars by two accounts on the same external URL. I found that something like this was needed to make it work somehow.

Thanks Frank,

Both fixes have been applied to my tree now.

Regards,
Andrew.
