As discussed previously, the headers in the HTTP request may be more  
relevant to compress, since you want to fit as many requests as possible  
in the initial TCP window. In the response the headers are many times  
dwarfed by the size of the actual resource. Getting a representative  
sample for test purposes quickly gets difficult for privacy reasons, in  
particular if you capture mobile traffic, where unique identifiers like  
phone number could be added to the requests by the network operator.
