manipulating headers in pre-processor
Hi, I have written a pre-processor that modifies headers on an HTTPSampler (I need to do this because the header is dynamically derived), but the call getHeaderManager() on the HTTPSampler object always returns null. Even if I have actually created a HeaderManager in the test configuration. Creating a new HeaderManager object and programmatically calling setHeaderManager on the HTTPSampler object in my preprocessor doesn't do anything either. Is there a way to dynamically modify outgoing request headers?

Ok, I moved the manager.add(header) call up above
sampler.setHeaderManager() to ensure that the manager being set in fact
has at least one header already in it. The manager object subsequently
retrieved is indeed the same object (object hashcode) that was set (I
checked just for sanity). But the header is still not coming through.
Next step is rebuilding JMeter with some extra debugging I suppose.

Ah, that helps greatly.
try putting the headers into the manager and then calling
sampler.setHeaderManager(manager). JMeter is doing lots of funky things
during test runs. In essense, it's searching your header manager for headers
and finds none, so it gets tossed. It does this because values from multiple
headers potentially have to be merged (in a certain order) and the sampler
has to be returned to original condition after each run - all without cloning
objects all over the place.

Ah, that helps greatly.
try putting the headers into the manager and then calling
sampler.setHeaderManager(manager). JMeter is doing lots of funky things
during test runs. In essense, it's searching your header manager for headers
and finds none, so it gets tossed. It does this because values from multiple
headers potentially have to be merged (in a certain order) and the sampler
has to be returned to original condition after each run - all without cloning
objects all over the place.

It's not.
public void process() {
...
Header header = new Header("Authorization", authstring);
HeaderManager manager = sampler.getHeaderManager();
if (manager != null) {
manager.add(header);
} else {
log.error("No header manager configured for sampler: " + sampler);
manager = new HeaderManager();
sampler.setHeaderManager(manager);
manager.add(header);
System.out.println("manager size: " + manager.size());
for (int i = 0; i < manager.size(); i++) {
System.out.println("header: " + manager.get(i));
}
System.out.println("manager: " + sampler.getHeaderManager());
}
My header is indeed in the manager as the loop proves, but it is not coming out in the request (although I can see the fixed user-agent header I set through a HeaderManager GUI). Can anybody else verify this? (I tried with a header named something other than "Authorization" just in case, and it doesn't come through either)

It's not.
public void process() {
...
Header header = new Header("Authorization", authstring);
HeaderManager manager = sampler.getHeaderManager();
if (manager != null) {
manager.add(header);
} else {
log.error("No header manager configured for sampler: " + sampler);
manager = new HeaderManager();
sampler.setHeaderManager(manager);
manager.add(header);
System.out.println("manager size: " + manager.size());
for (int i = 0; i < manager.size(); i++) {
System.out.println("header: " + manager.get(i));
}
System.out.println("manager: " + sampler.getHeaderManager());
}
My header is indeed in the manager as the loop proves, but it is not coming out in the request (although I can see the fixed user-agent header I set through a HeaderManager GUI). Can anybody else verify this? (I tried with a header named something other than "Authorization" just in case, and it doesn't come through either)

Making a new HeaderManager and calling setHeaderManager
