[Laszlo-dev] Re: [Laszlo-user] Load testing ...

[Eric Bloch]

Jon,


For XML-over-HTTP style  apps, it's easiest simple to hand-build up a 
list of urls for a session and use a tool like Jef Poskanzer's httpload.

For SOAP and requests with post bodies, it's painful.

That said, I have a simple design in mind for something that would be 
great I think.  I've been investigating Apache JMeter and I really like 
it and plan to use it on a project here.  The idea I have would be to 
implement a Java Filter (see the servlet spec) that is inserted into the 
lps-enabled webapp before the LZServlet.  You could then catch all 
incoming requests for a given session, read/parse the special formed 
urls, read any incoming POST bodies, and create an input file for apache 
jmeter to run later.

This could be used for both server regression and server performance 
testing.

We don't currently document the url protocol between the client and the 
LZServlet though.  But it is simple.
