Nikola Petrov commented on HTTPCLIENT-1312:
-------------------------------------------

I suspected that it might be linkedin's fault. I also saw the content-length: 0 but thought that httpclient should check the content size before passing it to GZipInputStream which checks for a magical header in the opening phase. Thanks for the quick response.

Besti, Nikola

> We are a having a problem with the httpclient implementation on redirecting websites that support gzip encoding. The problem occurs only if the automatic redirect facilities are disabled. Here is a resulting code that fails - note that if you set the HANDLE_REDIRECTS to true it works
