I'm not familiar with sponsoring QGIS development. The sponsorship page makes it sound like there's an annual commitment and there's no indication of how to direct funds for a specific task:
http://qgis.org/en/site/getinvolved/governance/sponsorship/sponsorship.html Perhaps a kickstarter campaign would be better? I personally would donate my own time/money to get this fixed. Maybe others would too. In any event (sponsorship vs kickstarter), we would need to know much money I would need to raise to support this initiative. Thoughts/suggestions? Thanks, Peter From: G.

The time is enough for fixing but I suspect that, if no dev is working on it at the moment, a sponsorhip would be the right solution. 2015-03-31 12:01 GMT+02:00 Peter Borissow <peter.boris...@yahoo.com>: Thanks Giovanni- Do you know when the dev team is planning the next release? I wonder if there's time to get this fixed before the next release. Peter From: G.

To cache a whole WFS and start seems overboard, in that case why wouldn't you just download the data set. BBOX is a must for web services as a main part of the purpose is to allow users to only grab the part they need when they need it.
