GZIP: pjl-comp-filter vs build-in compression engine

[Ilya Kazakevich <ka...@devexperts.com>]

Hello.
 
Http connector is able to compress data ("compress" param), right?
So, why filters like pjl-comp-filter exist?
 
Did anybody compare them? Any benchmarks or pitfalls? 
 
I am asking because some people in our company uses pjl, and I do not
understand why do I need some third-party solution, if from-the-box
functionality exists.
 
What do you think?
 
Thanks.

I can think of two reasons:

1. At one point, the gzip capability in Tomcat didn't exist (?)
2. It's easier to configure a compression filter that isn't
   tied to a servlet container ONCE rather than having to rely
   on a different setup if you migrate between containers.

Why not ask those people why they use that third-party library?
