[DeleGate-En] DeleGate/9.0.1(ALPHA) -- dynamic linker and improved SSL performance and usability

Dear DeleGate users,

I inform you of the new release of DeleGate available as follows:
 DeleGate/9.0.1(ALPHA) -- dynamic linker and improved SSL performance and usability

Simplified Installation

From DeleGate/9.0.1, the SSL libraries has come to be linked dynamically
into DeleGate process, and then executed in it. No compile time environment
is necessary to make it. Also DeleGate after 9.0.1 includes a built-in
anonymous certificate which can be used as a default certificate to ease
instant setup of a TLS gateway without preparing a certificate. At the
run-time, if the dynamic library of SSL are not at the standard location,
it can be specified with newly introduced DYLIB parameter.

Refined Performance

The performance of TLS with DeleGate has significantly refined in
DeleGate/9.0.1, about ten times faster than older versions. The context and
sessions of SSL has come to be cached and shared.

Simplified Configuration

From DeleGate/9.0.1, the configuration of DeleGate as a TLS (or SSL) gateway
has become simple and uniform. TLS gateways for any application protocol
including HTTP, FTP, SMTP, POP, IMAP and so on, can be enabled by simply
specifying the common STLS parameter as this:
