globalAgent not defined

Hi,
I am using browserify, and I am facing an issue with some modules (example node-couchdb) that require the http module.
The error is Cannot set property 'maxSockets' of undefined
After some debugging, it seems that globalAgent is not defined in the http-browserify module.
Do you have any hints regarding this issue? Do you think this can fixed on your side?
Thank you

Start by reproducing the error with browserify, node-couchdb, and the http module, then inspect how the http-browserify module handles globalAgent. Confirm the expected behavior for maxSockets and verify that the example no longer throws when the fix is complete.
