* Issue #586 Enhancement for detection of insufficient threads
Do not count acceptors and selectors at server level if connector uses own dedicated thread pool
Signed-off-by: vladimir.bukhtoyarov <jsecoder@mail.ru>
ConnectionFactories may be added after the connector is started.
As such there is always the possibility that creating a new
connection fails because there is no available ConnectionFactory for
that protocol.
Rather than failing with an IllegalStateException instead of a
NullPointerException, we now check at connector start whether the
SslConnectionFactory is properly configured.
This should catch 99% of the cases, where the connector is
misconfigured, reporting the error earlier and explicitly
(connector does not start) rather later and hidden (connection cannot
be created).
Now testing the return value of onEarlyEOF() and calling the
application when the value is true.
This means that the application can now consume the early EOF and the
spin does not happen.
* Issue #844 DoS Handler
First cut at implementation of Thread limiting handler for #844
* Added modules, simplified API, added IP exemptions
* fixed xml
* fixed preallocation
* simplified code
Added addCSV method to HttpFields to more efficiently add values to a CSV field without duplicates.
Improved usage of QuotedCSV and removed older parsing
Used new method in GazipHttpOutPutInterceptor to avoid duplicate Vary fields
If a request is not handled within the scope of the GzipHandler, the gzip interceptor is removed so it cannot be used by any subsequent handlers.
If the request is handled, it is left in place to be used by any async handling.
The new IPv6 capable InetAddressSet has been added as an alternative for IPAddressMap
The IncludeExclude class has been generalized to IncludeExcludeSet that can have a different
Predicate type to the set type and this works well with InetAddressSet.
However for #881 and #883, this may not be enough and Map semantics may need to be added.
The IPAccessHandler also has path mappings supported, which could need the map semantics, so for now a new InetAccessHandler has been
added that just uses an IncludeExcludeSet<InetAddressSet>, but this has yet to be tested.
The AbstractProxyServlet uses a host:port combinations, so IncludeExcludeSet<InetAddressSet> is not directly applicable.
