Sending binary data in HTTP Request body

[Isabel Beltran <ib...@hotmail.com>]

We are trying to use JMeter to load test an application which uses HTTP 
protocol through the CICS Web Interface to access a legacy 0S/390 
application. The HTTP request body contains binary data, it does not contain 
name/value pairs. Is there any way that the HTTP request sampler could 
accept binay data as the body of the request?.

Reading through the mailing list appends, we were trying to find out how to 
achieve this. It seems that the best solution - in case the HTTP request 
sampler could not help us - will be to code our own Java Sampler or 
BeanShell script. Are we right?. Which is the best approach?. Is there any 
docs/references available on how to extend AbstractJavaSamplerClient apart 
from the SleepTest class?.

Thanks in advance, regards

Isabel

Is this a POST or a GET command?
Indeed is it valid HTTP?

If it's not a valid HTTP request then it may not be possible to
persuade either the standard HTTP Protocol handler or the Apache
HTTPClient handler to send the data, in which case it would be
necessary to write a new sampler. However, if it is valid HTTP, but
the existing samplers don't work, then please raise a bug report.

We needed to support a private protocol which uses text messages over
TCPIP.  (Not HTTP) I wrote that as a version of the JavaTest Sampler,
but in retrospect this was not the best approach.

I'd recommend looking at the TCP Sampler as a basis instead.

Or you could write it in BeanShell - this is especially useful for
prototyping, as you can write a stand-alone script and test that, and
then plug it into the sampler.
