How to add a permalink in full view of record (OPAC)?

You have the possibility to add a permalink by adding the following line to xxx01/tab/edit_doc_999.lng:

! 1 1 1
!1 2 3 4 5 6 7 8 9 0 11 2 13 4 15 16
!!-!!!!!-!-!!!!!!!!!!-!-!-!!!!!!!!!!!!!!!!!!!!-!-!-!!!-!-!!!!!-!-!!-!!
## DRL D LDirect Link Y S E W

Required expand routine is expand_doc_link_to_doc which should be added to xxx01/tab/tab_expand e.g. for WEB-FULL:

WEB-FULL expand_doc_link_to_doc

The link (field) produced looks like this (example from our Ex Libris test environment):

DRL L $$ahttp://il-aleph20.corp.exlibrisgroup.com:899n/F/?func=direct&doc_number=000002345&local_base=

The server name comes from the variable $WWW_HOST, file $alephe_root/aleph_start

echo $WWW_HOST
il-aleph20.corp.exlibrisgroup.com
