Significant contributions to the HAProxy project in forms of code, time or funding (as of 2010/01/12)

Some happy users have contributed code which may or may not be included. Others spent a long time analysing the code, and there are some who maintain ports up to date. The most difficult internal changes have been contributed in the form of paid time by some big customers who can afford to pay a developer for several months working on an opensource project. Unfortunately some of them do not want to be listed, which is the case for the largest of them.

Code and fixes

I don't update this list very frequently. If you want your contribution to be noted here, please contact me. If you want to suggest a useful feature, please discuss it on the mailing list. If your company wants to fund a specific development and wants to be added here, please first contact me so that I can tell you whether I'm aware of a similar work in progress. If you are one of the funding companies listed below and want to add your logo, please send me a small one. By "small", I mean one which will not deform the table.
