Default parameters (user-agent)
Hi,
I'm using the httpclient 4.0.1 library in an application and I've been
looking for a way to set default parameters, but haven't found it in the
4.x API.
I could set the user-agent after each creation of HttpClient, but then
third party libraries I use (oauth-signpost) that use httpclient don't
have the user-agent set.
Is there a way to set default parameters?
Kind regards,
- Willem van Engen

That makes sense, thanks. That means that libraries using httpclient
should generally provide an api to set httpclient parameters.
Kind regards,

It was a conscious design decision which is unlikely to change. Absence
of static / global code helps ensure HttpClient can work correctly in
managed environments such as JEE containers with a complex class loader
hierarchy.

Hi Oleg,
Thanks for your explanation. Just curious to know if this was a design
decision, or if it might change in the future.

Willem,
HttpClient 4 does not provide a means of setting global parameters. You
can provide a custom HttpClient implementation that pre-populates
certain default parameters upon instantiation and use this class across
your application. Those parameters, however, will not apply to 3rd party
libraries if they create HttpClient instances internally.
