How to emulate a real http request via cfhttp?
I need to emulate a real http request via cfhttp. I was getting rss feed with ColdFusion, but tonight they started to block my request and send an index page in response instead of rss fead.
I added useragent for cfhttp, but it doesn't help.
Opera, Firefox and Chrome open feed correctly from the same computer.
Answer
Yep, thanks. I sniffed all HTTP headers which browser sends to the site and then emulated them in cfhttp request. The solution is:
<cfhttp url="http://example.com/feed"
useragent="Mozilla/5.0 (X11; U; Linux i686; en-US) AppleWebKit/533.7 (KHTML, like Gecko) Chrome/5.0.391.0 Safari/533.7"
result="httpresult"
redirect="false"
