EDIT

requests like http://test.e-taxonomy.eu/cdmserver/phycobank_production/registrationDTO/identifier/http%+3+A%2F%2Fphycobank.org%2F100105.json

are rejected by apache with a http 404 code. This blocks from resolving http identifiers like http://phycobank.org/100105.

By default apache does not allow %2F for / and %5C for \ in URLs:

• http://httpd.apache.org/docs/current/mod/core.html#allowencodedslashes

The AllowEncodedSlashes-Direktive for apache can be set in the server configuration and also in vhost configurations:

  #
  # NOTE: AllowEncodedSlashes is off per default to prevent possible security vulnerabilities.
  #       To allow the cdmserver resolving http identifiers via HTTP GET requests it is required to 
  #       allow encoded slashes. See https://dev.e-taxonomy.eu/redmine/issues/7563  
  #
  AllowEncodedSlashes On
