search profiling showed, that a major amount of time is wasted by computing url hashes. The computation does an intranet-check, which needs a DNS lookup. This caused that each urlhash computation needed 100-200 milliseconds, which caused remote searches to delay at least 1 second more that necessary. The solution to this problem is to attach a URL hash to the URL data structure, because that means that the url hash value can be filled after retrieval of the URL from the database. The redesign of the url/urlhash management caused a major redesign of many parts of the software. Since some parts had been decided to be given up they had been removed during this change to avoid unnecessary maintenance of unused code.

- SSIs may now refer to servlets, not only files
- calling a servlet, the servlet/SSI engine is called recursively
- SSIs now work also for non-chunked-encoding supporting clients
This will support the new search page functionality, to show search results
dynamically without using javascript. To test this method, a test page has been added
http://localhost:8080/ssitest.html
..calls dynamicalls 3 servlets, which produce some delays during their execution
please verify that you can see the result step-by-step on your browser
To implement this feature, some refactoring had been taken place, mostly code
had been made static and will execute faster.

- different handling of link quotation
- different handling of link normalization
- enhanced html/unicode en/de-coding

- added chunked file transfer for non-yacy clients
- SSIs are streamed using chunked transfer, partly delivered pages can be seen in browser before transmission is finished
- added client-side network unit identification
- cleaned up code

- all requests to the own httdp can now be listed in the access tracker menu
- the search statistics had been renamed to access tracker and extended by this tracker

- all web page parsing operations will now increase a web structure file
- the file is computed in memory and dumped at shutdown-time to PLASMASB/webStructure.map in readable form (not a database)
- the file can be used externally to analyse the link structure of the crawled pages
- the web structure can also be retrieved using a xml-interface at http://localhost:8080/xml/webstructure.xml
- the short-term purpose is the computation of a link-graph image (before linuxtag!)
- a long-term purpose could be a decentralized computation of the citation rank

- better memory allocation for FlexTable indexes
- splitting between static index and dynamic index (only the dynamic part must grow)
- to enable a merge-iteration of new splittet index, a huge number of classes needed to be adopted for new iterator classes
- added new iterator classes that support cloneable iterators
- adopted all iterator classes to implement cloneable itarators

- better errorhandling
- adding support for outgoing transfer- and content-encoding
- avoid holding outgoing messages into memory before sending them

Extracted text of files that are larger than 5MB is stored in a temp file instead of keeping it in memory
*) plasmaParserDocument.java; getText now returnes an inputStream instead of a byte array
*) plasmaParserDocument.java: new function getTextBytes returns the parsed content as byte array
Attention: the caller of this function has to ensure that enough memory is available to do this
to avoid OutOfMemory Exceptions
*) httpd.java: better error handling if the soaphander is not installed
*) pdfParser.java:
- better handling of documents with exotic charsets
- better handling of large documents
- better error logging of encrypted documents
*) rtfParser.java: Bugfix for UTF-8 support
*) tarParser.java: better handling of large documents
*) zipParser.java: better handling of large documents
*) plasmaCrawlEURL.java: new errorcode for encrypted documents
*) plasmaParserDocument.java: the extracted text can now be passed
to this object as byte array or temp file

This shall be seen as an experiment to exclude all cases where
there could be a DNS lookup during URL comparisment.
