SSLBSIZE (JANUS DEFINE parameter)

<section begin="desc" />SSLBSIZE xxxx -- Size of input/output buffers on SSL port<section end="desc" />

SSLBSIZE is a parameter on JANUS DEFINE, which defines and sets characteristics of a Janus port.

This tuning parameter specifies the size of the input buffer used for reading encrypted data for an SSL port. An SSL port is a Janus port whose definition includes an SSL parameter, which indicates that communications on this port may be encrypted using Janus Network Security SSL (Secure Sockets Layer) or TLS (Transport Layer Security) support.

The SSLBSIZE parameter also specifies the size of the SSL output buffer. To set the input and output buffer sizes independently, you use the SSLIBSIZE and SSLOBSIZE parameters.

The default for SSLBSIZE is 4096 bytes; the minimum and maximum values are 1024 and 32767, respectively.

If you set SSLBSIZE greater than the SSL specification maximum buffer size of 16000, the port's input buffer size is set to the SSLBSIZE value, but the output buffer size is set to 16000 bytes. Setting the input buffer greater than 16000 bytes might be necessary if the port will have connections with SSL implementations that don't fully conform to the SSL specification. For more information about buffer sizing and about Janus handling of oversized packets, see SSLIBSIZE and SSLOBSIZE.

SSLBSIZE is valid for SRVSOCK, WEBSERV, OPENSERV and SDS port types.
