[opencms-dev] Absolute links to different webapps in same server as site root gets changed to relative links

[Nacho Fernández]

Hi again. Thank you so much for the hint! Even not being the ideal way 
to tackle the issue (specially when the apps deployed vary a lot), it 
actually works nicelly. It is important to notice that the file 
/system/config/linkexcludes can be edited from the OpenCms workplace, 
but it requires changing the file opencms-importexport.xml, switching 
the <linksustitutionhandler> content from class 
org.opencms.staticexport.CmsDefaultLinkSubstitutionHandler to class 
org.opencms.staticexport.CmsAdvancedLinkSubstitutionHandler.

If someone else knows of a way of configuring this behaviour in a more 
general way it would be great to know about it.
