Yes, your header has set a new world record : 58 kB ! Many systems will never accept more than 4kB in a single header. Apache accepts up to 8kB. Haproxy accepts 8kB by default for a whole request, so the header itself was larger than the maximum request. Also, there are 1000 different values in this header, some products will experience issues because this is the same as concatenating 1000 times the same header and some products have low limits on the number of headers (typically 100). You can workaround this for now by setting "tune.bufsize 65536" and "tune.maxrewrite 1024" in your global section, but if I were you, I'd fix the application before putting it into production so that it does not do such stupid things, otherwise it will be a nightmare to maintain and debug in the long run.
