setHeaders: Set headers

In johndharrison/bmproxy: Wrapper around the 'BrowserMob Proxy' REST API for R

Description

Set and override HTTP Request headers. This sets the headers that will set by the proxy on all requests

Usage

setHeaders(proxy, headers = list(), ...)

Arguments

proxy	An object of class "proxy". A proxy object see proxy.
headers	A named list. The name of an item is the header name (such as "User-Agent") and value is a value of HTTP header to setup (such as "BrowserMob-Agent"). Example: list("User-Agent" = "BrowserMob-Agent")
...	Additonal function arguments

Value

invisible(proxy): An object of class "proxy" is invisibly returned. A proxy object see proxy. This allows for chaining from this function to other functions that take such an object as an argument. See examples for further details.
