61e04fc01027 Initial import of the nginx.org website. Ruslan Ermilov <ru@nginx.com> parents: diff changeset	60 SSL operations consume extra CPU resources.
61e04fc01027 Initial import of the nginx.org website. Ruslan Ermilov <ru@nginx.com> parents: diff changeset	61 On multi-processor systems you should run several worker processes:
61e04fc01027 Initial import of the nginx.org website. Ruslan Ermilov <ru@nginx.com> parents: diff changeset	62 no less than the number of available CPU cores.
61e04fc01027 Initial import of the nginx.org website. Ruslan Ermilov <ru@nginx.com> parents: diff changeset	63 The most CPU-intensive operation is the SSL handshake.
61e04fc01027 Initial import of the nginx.org website. Ruslan Ermilov <ru@nginx.com> parents: diff changeset	64 There are two ways to minimize the number of these operations per client:
61e04fc01027 Initial import of the nginx.org website. Ruslan Ermilov <ru@nginx.com> parents: diff changeset	65 the first is by enabling keepalive connections to send several
61e04fc01027 Initial import of the nginx.org website. Ruslan Ermilov <ru@nginx.com> parents: diff changeset	66 requests via one connection and the second is to reuse SSL session
61e04fc01027 Initial import of the nginx.org website. Ruslan Ermilov <ru@nginx.com> parents: diff changeset	67 parameters to avoid SSL handshakes for parallel and subsequent connections.
61e04fc01027 Initial import of the nginx.org website. Ruslan Ermilov <ru@nginx.com> parents: diff changeset	68 The sessions are stored in an SSL session cache shared between workers
61e04fc01027 Initial import of the nginx.org website. Ruslan Ermilov <ru@nginx.com> parents: diff changeset	69 and configured by an <dirname>ssl_session_cache</dirname> directive.
61e04fc01027 Initial import of the nginx.org website. Ruslan Ermilov <ru@nginx.com> parents: diff changeset	70 One megabyte of the cache contains about 4000 sessions.
61e04fc01027 Initial import of the nginx.org website. Ruslan Ermilov <ru@nginx.com> parents: diff changeset	71 The default cache timeout is 5 minutes. It can be increased by using
61e04fc01027 Initial import of the nginx.org website. Ruslan Ermilov <ru@nginx.com> parents: diff changeset	72 the <dirname>ssl_session_timeout</dirname> directive.

61e04fc01027 Initial import of the nginx.org website. Ruslan Ermilov <ru@nginx.com> parents: diff changeset	103 Some browsers may complain about a certificate signed by a well-known

61e04fc01027 Initial import of the nginx.org website. Ruslan Ermilov <ru@nginx.com> parents: diff changeset	105 without issues.
61e04fc01027 Initial import of the nginx.org website. Ruslan Ermilov <ru@nginx.com> parents: diff changeset	106 This occurs because the issuing authority has signed the server certificate
61e04fc01027 Initial import of the nginx.org website. Ruslan Ermilov <ru@nginx.com> parents: diff changeset	107 using an intermediate certificate that is not present in the certificate
61e04fc01027 Initial import of the nginx.org website. Ruslan Ermilov <ru@nginx.com> parents: diff changeset	108 base of well-known trusted certificate authorities which is distributed
61e04fc01027 Initial import of the nginx.org website. Ruslan Ermilov <ru@nginx.com> parents: diff changeset	109 with a particular browser.
61e04fc01027 Initial import of the nginx.org website. Ruslan Ermilov <ru@nginx.com> parents: diff changeset	110 In this case the authority provides a bundle of chained certificates
61e04fc01027 Initial import of the nginx.org website. Ruslan Ermilov <ru@nginx.com> parents: diff changeset	111 which should be concatenated to the signed server certificate.
61e04fc01027 Initial import of the nginx.org website. Ruslan Ermilov <ru@nginx.com> parents: diff changeset	112 The server certificate must appear before the chained certificates
