> We found that some web customers were unable to access the puzzle, and found the cause of the problem to be App Engine’s limit on the size of outbound request headers (16KB). Users with a large amount of third-party cookies had their identity stripped from the proxied request. We made a quick fix to proxy only the headers and cookies we needed and we were back in action.
That’s pretty funny. Users of NYT are sending request headers with sixteen kilobytes of tracking data. Maybe that’s the real problem eh?
I wonder which news website has the largest amount of trackers. If I let the CNN home page sit open in chrome, I can come back an hour later and find thousands of requests blocked by uBlock.
