yacy_search_server/htroot/CacheResource_p.java
orbiter 536e77e8b7 modifications towards a single database operation to read/write http header and cached file at once:
- 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)
