Nginx : For Http range request ie 206 , custom headers are blocked in case of x-redirect chain -


we came across strange behavior when wanted etag propagated through x-redirect chain part of http response range request ie http 206.it seems nginx filters out additional costume headers / tmp variable part of final response through x-redirect non-200 response. kindly suggest workaround issue.

here's log data under debug mode normal vs range request clearing showing custom headers being filter out.

both of responses have

accept-ranges: none

indicates server doesn't support range request.

reference: http://www.w3.org/protocols/rfc2616/rfc2616-sec14.html

  servers not accept kind of range request   resource may send        accept-ranges: none    advise client not attempt range request.

dont know nginx config. because http 1.1 supports range request, guess might have missed directive:

 proxy_http_version 1.1;

nginx proxy module default uses http 1.0. however, if upstream server supports http 1.1 (it should), it's recommended use 1.1 better performance. see reference detail: http://wiki.nginx.org/httpproxymodule#proxy_http_version

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
