Would it be feasible/possible to add new event hook prior to request being made

Prerequisites

• I am using the latest version of Locust
• I am suggesting a new feature, not asking a question

Description

I am specifically interested in seeing if it is feasible to build additional event hook to fire off prior to request in locust being made. Inverse of this hook https://docs.locust.io/en/stable/api.html#locust.event.Events.request Available hook is fired when request is completed, this would fire prior to request being made.
In particular my use case is to be able modify request headers in bulk/conditionally. Has a request like this come in at all? Would this be feasible to build out.

Hmm... I think what you want is just to wrap the calls in a subclass. See the subclasses at the end of this file for example:

locust/examples/rest.py

Line 78 in 63bfdc7

class RestUserThatLooksAtErrors(FastHttpUser):

Thank you. This surely helps with fasthttpuser class. Would there be equivalent way to
Wrap HttpUser class. I am having hard time figuring out which method can be used on the class tho pass in additional headers.

If you just want to set default headers in HttpUser, you can try self.client.headers = {'user-agent': 'Mozilla/5.0 ...'} (havent tested it myself)
