- removed distinction between header file types for http and ftp; ftp is simulated by using http properties - removed all old resourceInfo classes that handled this distinction - introduced a new distinction between http request and http response objects - unified new response objects with two other object types that had been introduced elsewhere - changed all servlet call methods to use the new http request header object type - divided static object keys for http header properties into request and response types - refactoring here and there (a large number of type changes and many methods merged/moved) git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@5079 6c8d7289-2bf4-0310-a012-ef5d649a1542
