I have a strange bug with mitmdump both on release and 4.0.0.dev169
I’m running it with mitmdump -p 8888
I can reproduce the bug on this url
https://search.tez-tour.com/tariffsearch/refs?callback=jsonp1522770924501&_=1522770924725&locale=ru&rfCityId=345
also reproduces on another url on another host
the bug is that sometimes mitmdump returns 502 Bad Gateway
here is request (curl bash copy) but bug is in browser:
curl 'https://search.tez-tour.com/tariffsearch/refs?callback=jsonp1522770924501&_=1522770924725&locale=ru&rfCityId=345' -H 'Accept-Encoding: gzip, deflate, br' -H 'Accept-Language: ru-RU,ru;q=0.9,en-US;q=0.8,en;q=0.7' -H 'Upgrade-Insecure-Requests: 1' -H 'User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3325.181 Safari/537.36' -H 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8' -H 'Cache-Control: max-age=0' -H 'Cookie: aid=BF72DA5E8AA6C7EC07339A1D83824B19A44D589E20180403185058.m08; agency_auth_ga=true' -H 'Connection: keep-alive' --compressed
