The user can select if the request should use HTTP 1.0 or 1.1, or send the entity as chunked or using 'Content-Length' encoding, if the '100-Continue' expect handshake should be used-or-not, if HTTP KeepAlive should be used or not, and if response compression (i.e. GZip) is requested. If the request is over SSL, you could also turn off SSL Trust and Hostname verification for testing purposes - such as when using test certificates. Additionally, it can also use an identity certificate if 2-way SSL is requested.
To make this even better, the ToolBox also offers a HTTP/S Load test version of this same utility - that can be used to load test REST, SOAP, Hessian or any kind of payload over HTTP/S. This Load Test utility is a clone of the popular Apache Bench load test client - but much more advanced and stable!
The ToolBox also includes a TCP Dump utility - that can be used to view requests over the wire - in both HEX and Text formats. It additionally introduces support to capture a request into a file - which allows one to capture any kind of request message - even WS-Secured messages, Hessian binary messages etc, which can then be used with the JavaBench - to run a load test against your services.
For those who really knows what they are doing, and for example if you would like to test your ESB or SOA server for its support against malicious or malformed requests - there is a Raw socket client.
This allows one to hand-craft a HTTP request as you wish! The ToolBox also hosts a module that will start one or more Jetty servers with sample applications, which could then be used to test your ESB or SOA services. Starting multiple instances over different ports allows one to easily test load balancing and fail-over options of your ESB.
Finally the ToolBox allows you to start an instance of the UltraESB - the ultimate ESB that is simple to use, but supports ultra performance! Do read the full article "Getting started with the AdroitLogic ToolBox for the UltraESB" and follow through the end-to-end sample to get started.
