java - How to know whether a URL request for my website is from browser or from a automated program -


my requirement know whether request webpage genuine request (through browser ) or automated request generated through java program. can differentiate request type?

actually need block requests generated program hence searching difference.

there no fool proof way of doing this. effective solution me was:

  1. implement user agent check @ web server level (yes not fool proof). target block out known / common programs people use hit urls. libperl, httpclient etc. should able build such list access logs.

  2. depending on situation, may or may not want search engine spiders crawl site. add robots.txt server accordingly. not spiders / crawlers follow instructions robots.txt, do.

  3. use specialized tool detect abnormal access site. https://www.cloudflare.com/ can track access site, , match ever growing database of known , suspected bots.

note: in no way affiliated cloudflare :)

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 ...
