but what i need is just the basic http headers such as

“HTTP_HOST”=>“localhost:3000”
“HTTP_USER_AGENT”=>“Mozilla/5.0 (X11; U; Linux i686; en-US;
rv:1.9.2.12)
Gecko/20101027 Ubuntu/10.04 (lucid) Firefox/3.6.12”,

Not the rails related headers such as

“rack.errors”=>#IO:0xb789c558
#<ActionController::Response:0xb61677e8 @session={:admin=>#<User id: 1,
mail: “[email protected]”, password: “3ac29c8db9ca98e0e4d782bffc7acd94”,

:session_id=>“08f6c3b78700a2bce362b79853cb3dfa”, “flash”=>{}},

is their anyway to get this…

Thanks

The headers you’re looking for should be available in request.env

request.env[“HTTP_ACCEPT”]
request.env[“HTTP_HOST”]
request.env[“HTTP_USER_AGENT”]

hi ,
Thanks for your reply,but still i got the rails related headers such as

“rack.session”=>{:admin=>#<User id: 1, mail: “[email protected]”, password:
“3ac29c8db9ca98e0e4d782bffc7acd94”, lname: “admin”, fname:

loginid: “adminldap”, created_at: “2011-02-28 12:25:47”, updated_at:
“2011-02-28 12:25:47”>,

is their anyway to get only basic http headers exactly,the below is th
o/p
of request.env

I guess I’m not understanding the question.

If you want to access a HTTP header such as HTTP_USER_AGENT, you can
just
pull it out of the request.env hash:

puts request.env[“HTTP_USER_AGENT”]

Does it matter that there are other rails keys in the hash?

You can also print all the headers beginning with HTTP by using match if
you
want:

<% for header in request.env.select { |key, val| k.match("^HTTP.*")} %>
<%= key %> <%= val %>
<% end %>

5

Sorry, that example should have been

<% for header in request.env.select { |key, val| k.match("^HTTP.*")} %>
<%= header[0] %> <%= header[1] %>
<% end %>
