jmeter header manager remove header

Question

I have a large and deep test and am using jmeter 2.1.3.

I have a default http header manager at the top level and inherited for all the samplers below.

Deep in the test structure i need to make an http request and remove all the headers inherited from the parent manager.

The docs say this is achieved by creating a child manager for this sample and declaring the header with a null value, however this just sends a null value over the air and doesnt strip the header completely from the request.

Any ideas? I really dont want to create a child manager for every sample just to over come this issue as im often tweaking the values to 99% of the samples

Answer 1

Found a cool way to sort it, as i just couldn't get the header manager to do what i think its meant to from the docs. I added a BeanShell PreProcessor to the sampler i didn't want an inherited header to be used at all with the following:

sampler.getHeaderManager().removeHeaderNamed("Authorization");

Adding this as a child will only make the script affect the current sampler and would not impact the default if it was set.

Answer 2

In your header manager at the top level, you could set the values as a variable, then later change that variable in a beanshell script.
