*) Replacing jsch 0.1.19 lib with newer version 0.1.21 *) Replacing PDFBox 0.7.1 lib with newer version 0.7.2 *) Refactoring of classes httpd/httpc/httpHeaders to make many methods for httpHeader/Requestline parsing reusable for new icap implementation *) adding chunked input stream support - needed by new icap implementation - needed by future httpc HTTP/1.1 support *) httpd.java - moving all connection property contants to class httpHeader - moving readHeader function to class httpHeader - moving parseQuery function to class httpHeader - moving handleTransparentProxy function to class httpHeader *) httpHeader.java - adding new fuction to parse the http response line - adding new function to converte http headers to a string that can be send to the client - adding a function that generates a proper url using all parsed connection properties *) ICAP Support - yacy now supports handling of icap response modification requests - this feature can be used by other icap enabled proxies to contact yacy as icap server, and to handover the downloaded content to yacy.logging for indexing - functionality was successfully tested with squid 2.5Stable 10 + icap patch - further icap services e.g. URL filtering based on yacy's blacklists are possible *) plasmaSwitchboard.java - htcache entries that are still needed for indexing are now properly registered as in use after system restart - extended logging: log message now shows parsing and indexing time for each sb. entry git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@757 6c8d7289-2bf4-0310-a012-ef5d649a1542
