"Nginx is an official work, the development of which since the beginning of the 2000s in the framework of labor relations with Rambler, was carried out by Igor Sysoev," Rambler told a Russian media site.

"Therefore, any use of this program without the consent of the Rambler Group is a violation of the exclusive right."

"It should be noted that programming was not part of my job responsibilities, but since there were time and traction, the first thing I did was adapt the patch to compress Apache responses," Sysoev said in that interview.

"Then, I was asked to deal with the mod_proxy module. I looked at it and decided it was easier to write everything from scratch than to adapt to some things there."
