In my module I'm creating a dynamic external link to launch a local FileMaker database client and run a FileMaker script that finds a record like so:
FMP://192.168.123.123/DatabaseName.fmp12?script=FindRecord&RecordID=12345
The problem is no matter whether I use the Drupal 7 link l()
function with attribute array absolute = true
or external = true
or if I assemble the link markup myself, either the anchor's href attribute gets stripped entirely or the protocol of FMP
gets replaced with HTTP
.
What do I need to do to let Drupal know this URL is safe to be outputted unmolested in outgoing emails?
