I have a situation where my first http\_poller logstash is getting a session id as output. Now in the second http\_poller call i need to carry that session id in the request header.
I am thinking of separating the two calls in two separate logstash processes. The first logstash will create the session and its output will be the session id over tcp/udp.
The second logstash after reciving the event - need to execute another http\_poller call to get the actual data. Now the challange is
- IN the second logstash instance how do i read the output over tcp and then pass it as header in the http\_poller call ?
Under these scenarios is there any thing else which you guys suggest ?

As far as I know the http poller is not able to use a dynamic input to form its request like you'd want it to do. (I'd love to be wrong. So please correct me, if I am!)
You could probably use a Ruby filter for this (not tested):
```
ruby {
init => "
require 'net/http'
require 'json'
"
code => "
uri = URI.parse('http://blablabla?session_id=' + event.get('[session_id]'))
response = Net::HTTP.get_response(uri)
if response.code == '200'
result = JSON.parse(response.body)
event.set('[data]', result)
end
"
}
```
