Re: Clustering without Apache in the front

Thanks Chris .. now I got a clear picture. First off I will try without cluster. If that does not work, I will go for clustering. Regards. On Tue, Jan 28, 2014 at 3:42 PM, Christopher Schultz < ch...@christopherschultz.net> wrote: > -BEGIN PGP SIGNED MESSAGE- > Hash: SHA256 > > Raquib,

Chris, Do you mean, if just the sticky session is used, tomcat clustering won't be needed? Thanks, Raquib Hasan On Tue, Jan 28, 2014 at 12:37 PM, Christopher Schultz < ch...@christopherschultz.net> wrote: > -BEGIN PGP SIGNED MESSAGE- > Hash: SHA256 > > Raquib, > > On 1/28/14, 12:29 P
