Class HttpRequestDecoder
java.lang.Object
org.jboss.netty.channel.SimpleChannelUpstreamHandler
org.jboss.netty.handler.codec.frame.FrameDecoder
org.jboss.netty.handler.codec.replay.ReplayingDecoder<HttpMessageDecoder.State>
org.jboss.netty.handler.codec.http.HttpMessageDecoder
org.jboss.netty.handler.codec.http.HttpRequestDecoder
- All Implemented Interfaces:
ChannelHandler
,ChannelUpstreamHandler
,LifeCycleAwareChannelHandler
Decodes
ChannelBuffer
s into HttpRequest
s and HttpChunk
s.
Parameters that prevents excessive memory consumption
Name | Meaning |
---|---|
maxInitialLineLength |
The maximum length of the initial line (e.g. "GET / HTTP/1.0" )
If the length of the initial line exceeds this value, a
TooLongFrameException will be raised. |
maxHeaderSize |
The maximum length of all headers. If the sum of the length of each
header exceeds this value, a TooLongFrameException will be raised. |
maxChunkSize |
The maximum length of the content or each chunk. If the content length
exceeds this value, the transfer encoding of the decoded request will be
converted to 'chunked' and the content will be split into multiple
HttpChunk s. If the transfer encoding of the HTTP request is
'chunked' already, each chunk will be split into smaller chunks if the
length of the chunk exceeds this value. If you prefer not to handle
HttpChunk s in your handler, insert HttpChunkAggregator
after this decoder in the ChannelPipeline . |
