Greetings,
I have been playing with HttpClient 4 lately. It is pretty nice piece of
software, but recently I run into problem I was not able to resolve.
Currently I am using HttpClient to provide communication between sistem I
am developing and some external one, which uses webservices with XML
responses.
After studying examples of HC - I decided to use DefaultHttpClient
httpclient = new DefaultHttpClient(); as field and reuse for consequent
requests to external system.
1st request works fine, but all the following requests fail with
exception:
org.apache.http.ProtocolException: Content-Length header already present

RequestContent.java:70)

However, if I make httpclient as local variable - it works totally fine.
Can someone explain, what am I doing wrong in the first place. I have a
feeling that something is not cleared after the first request. But I can
not figure out what specifically.
