Subject Re: DIGEST and BASIC authentication API
Date Sat, 02 Aug 2008 10:37:06 GMT
Thanks Oleg.

I have also installed the latest trunk version of http client in my
development system. Once 4.0-BETA is released, please release it in
the Maven repository also. I also believe this release will be
announced in this mailing list.
