Webrick override HTTPResponse::setup_header

Hi, all.

My subj solution:

class MyServlet < HTTPServlet::AbstractServlet
def do_GET(req, res)
class <<res
def setup_header()
… my code …
end
end

end

end

I think my solution is’t good and is’t true ruby way.
Another solution?

What are you trying to accomplish with this code?

Hi,

As Eric said, it’s not obvious what end result you are expecting but
it appears you want to change the headers of the response. If so, you
can do something like this:

class MyServlet < HTTPServlet::AbstractServlet
def do_Get(req, res)
res[“header_name”] = “header_value”

end
end

Webrick is not very well documented but the method names and their
source code are available here: http://ruby-doc.org/stdlib/

Hi andrey,

To clear out all of the existing headers you can use
res.instance_variable_set("@header", {“header_name” => “header_value”,
“other_header_name” => “other_header_value”})

Hi,

Generally you should reply to the ruby-talk list instead of one
particular person as someone on the list might have more knowledge of
this subject.

Are you sure that is the behavior of res[“header”]? The source code
does not look like it differentiates between pre-existing fields and
new fields. If you want to change the body of the response, use
res.body = “…”

Yes, but after exiting do_Get() Webrick add self headers:

 def do_GET(req, res)
    ...
     res.instance_variable_set("@header",
                              {"header_name" => "header_value",
                              "other_header_name" =>

“other_header_value”})

end

If you want to change the Content-Type, use

req[‘Content-Type’] = ‘application/x-my-world’
