[opencms-dev] Exclude directory from VFS

[Michael Emmerich]

Hello Kai,

yes this is possible.


1) In the opencms-importexport.xml config file, replace the line

  <linksubstitutionhandler>org.opencms.staticexport.CmsDefaultLinkSubstitutionHandler</linksubstitutionhandler>

with

  <linksubstitutionhandler>org.opencms.staticexport.CmsAdvancedLinkSubstitutionHandler</linksubstitutionhandler>


2) In your OpenCms, there is a file /system/config/linkexcludes/

in it, you can define those paths that are no identified as non-OpenCms, 
e.g. external to the application.


Example: Your OpenCms runs as the ROOT-Webappliciiton at 
https://www.myserver.com

Therefore everything starting with "https://www.myserver.com" will be 
seen as an internal Link in OpenCms. When you now do the configuration 
as above ans add "/myexternalapp" to the /system/config/linkexcludes/ 
config file,

https://www.myserver.com/myexternalapp will not be seens as an internal 
OpenCms link.


Hope this helps,

Michael
