SafeSquid for Linux SWG safesquid-2019.1026.1608.3-swg-standard released

From Secure Web Gateway


  1. ssl shutdown now simply sets the state, instead of waiting for completion of the ssl shutdown protocol.
    Users observed extremely large pile-up of connections queued up for closing. This was traced to long durations involved in the SSL shutdown protocol.
    SafeSquid now just sets the SSL shutdown state, instead of invoking the complete shutdown protocol.
    This behavior shall be changed in future when a better mechanism can be implemented to avoid the latency.
  2. ServerPool now uses heap memory instead of stack.
    The ServerPool that maintains idle connections to remote web-servers, for reuse is now moved to the heap memory.
    The legacy use of stack memory caused huge delays in release of unused memory.
    This should improve memory optimization.
  3. The update frequency is now a user configurable start-up parameter.
    Users can now alter the update frequency as per their individual needs.
    This frequency is now a configurable start-up parameter. The users can also trigger updates by sending signal USR1 to the SafeSquid process.
  4. Minimal changes done for installing SafeSquid on non-debian linux.
    The setup script has been minimally altered to support installation on Red-Hat Linux distributions.
