StreamCaching with slip not working
SampleProxySvc.zip
<http://camel.465427.n5.nabble.com/file/n5736044/SampleProxySvc.zip>
Camel version = 2.11.0
commons.httpclient version = 3.0.1
Attempting to implement a proxy service to route requests dynamically using
DynamicRouter pattern suggested by
http://camel.apache.org/dynamic-router.html.
I'm unsuccessful though in getting streamcaching to work. I've enabled
streamcaching on the CamelContext but when the proxysvc forwards the POST
request to my endpoint the body is always empty.
Attached is my code with two projects.
1. sample.proxysvc - Contains camel proxy
2. sample.restsvc - Simple rest servicSampleProxySvc.zipe
You will notice that proxysvc enables streamcaching on camel context in
camel-config.xml. When a POST request is made to sample REST service body
is always empty.
The only way i'm able to get it to work is by attaching a processor and
reading body into a string and setting setting in http request (Currently
this code is commented).
I'm sure i'm doing something wrong to enable stream caching. Hopefully it
is something easy that may be pointed out.
Thank You.

This is a bug in Camel and has been fixed recently. So will be fixed
in upcoming releases.

Stepping through code noticed that InputStreamRequestEntity is used during
post request.
A call to InputStreamRequestEntity.getContentLength leads to a call to
bufferContent because contentLength is set to CONTENT_LENGTH_AUTO. The type
of inputStream that is set in InputStreamRequestEntity is of type
InputStreamCache.
Because position is set to the end of the inputstream (see below) the call
to bufferContent results in buffer set to empty and the size is updated to
0. This causes POST request to always have an empty body.
this InputStreamRequestEntity (id=169)
buffer null
content InputStreamCache (id=146)
buf (id=154)
count 10
mark 0
pos 10
contentLength -2
contentType "application/json" (id=172)
Is this expected?
