Socket closed exception with one particular url

[Saurabh AMBASTA <sa...@lexmarkpartners-europe.com>]

Hi,

We are monitoring important urls using the httpclient. We are able to get 
a response from all urls except for one, where we get this exception The 
URL opens from IE. What could be the problem ?

[INFO] HttpMethodDirector - Retrying request

Hello,

try to make the HttpClient request as similar to the IE request as possible.
We've had a case where the value of User-Agent made the difference, but
some servers also fail if you send multiple cookies in separate headers
instead of folding them into a single one. Tracing SSL is a bit tricky,
but maybe you can use an SSL-enabled server with an echo servlet to check
what headers IE sends.

hope that helps,
  Roland
