Hi http://jmeter.apache.org/api/org/apache/jmeter/protocol/http/control/HeaderManager.html
so HeaderManager hm = sampler.getHeaderManager(); hm.clear(); If that doesnt work , you might need to call the size() method and then remove in a loop. regards deepak On Tue, Dec 6, 2011 at 8:00 AM, Jason Gilroy <[email protected]>wrote: > Thanks Deepak, this is so good it's almost magic.
