Hello, Developers!
1. What are the premises to use either
apache.coyote.http11.Http11NioProtocol or
org.apache.coyote.http11.Http11NioProtocol connectors?
There is no such protocol as "apache.coyote.http11.Http11NioProtocol" so
if you try using it, that connector will fail to start.
i assume you can guess that it's org.apache.coyote.http11.Http11NioProtocol
2. Do i get any advantages if i use Sync Servlet Api with
Http11NioProtocol connector
Yes.
What are they?
or do i have to use Async Servlet Api to get
the advantages?
No.
ok
3. How do i choose which one to use in any particular case?
a) Understand your requirements
b) Read the docs, particularly [1]
c) Choose the connector that best meets your requirements.
it's a bit abstract.
Java Blocking Connector Java Nio Blocking Connector
BIO NIO
Classname Http11Protocol Http11NioProtocol
Tomcat Version 3.x onwards 6.x onwards
Support Polling NO YES
Polling Size N/A maxConnections
Read HTTP Request Blocking Non Blocking
Read HTTP Body Blocking Sim Blocking
Write HTTP Response Blocking Sim Blocking
Wait for next Request Blocking Non Blocking
SSL Support Java SSL Java SSL
SSL Handshake Blocking Non blocking
Max Connections maxConnections maxConnections
It doesn't show how that corresponds to Sync vs Async Servlet APIs.
actually it's interesting to know about the following cases:
1. Sync Servlet + Non Bloking NIO Connector
2. Async Servlet + Bloking IO Connector
How are connector and servlet code related?
