hit rate in the cluster state? The simplest approach is that the polling policy of the payload uses Ip_hash to ensure that the same client is always distributed to the same node in the cluster, but this is not flexible enough. Therefore, it is necessary to use distributed caching to store session state in a cluster-shared redis.How to operate the TLS session information in Nginx, you can refer to the module in Openresty ssl_session_fetch_by_lua_block . See Https://github.com/openresty/lua-nginx

(CRL) or uses an online certificate status Protocol (OCSP) record. However, the problem with CRLs is that the list items of CRLs are increasing and need to be downloaded continuously. OCSP is more lightweight because it only gets one record at a time. The side effect, however, is that when you connect to the server, OCSP requests must be sent to a third party r

Check Protocol (rfc6960), which is used to query the CA site for certificate status, such as revocation. Typically, the browser uses the OCSP protocol to initiate a query request, the CA returns the certificate status content, and then the browser accepts that the certificate is in a trusted state.This process is very time consuming, because the CA site is likely to be abroad, the network is unstable, the RTT is also relatively large. Is there a way

This is why it is a good choice to use Zopfli in a way that does not become a resource, such files are generally compressed once and downloaded several times.is OCSP binding available?Having the server use OCSP stapling can increase the speed of your TLS handshake.

The current version of OPENSSL-1.0.2J does not support Google's CHACHA20 encryption algorithm. The CHACHA20 encryption algorithm is relatively safe relative to RC4, and is optimized for ARM's mobile phone, making it faster and more power-saving.However, the latest Intel processors and ARM V8 processors are optimized for AES-GCM encryption algorithms through the AES-NI instruction set, which is much faster than chacha20, so the Aes-ni encryption algorithm is preferred on devices that support AES-

certificate to the client, in principle, the client is to check the validity of the certificate from the CA, one but can not be verified (verify), will report the above error, and strict-ssl=false is to let npm not to verify, NODE_TLS_REJECT_UNAUTHORIZED=0 is to let node-gyp not to verify. So the two sides on the basis of a fake certificate in the HTTPS communication. In turn, it also shows that the agent I'm using has a MITM attack.Optimizations for other HTTPS HSTs: In short, it is i

. Optimize SSL/TLS access Although Ssl/tls is becoming more and more popular, its impact on performance should also be taken seriously. Its impact on performance is mainly reflected in two aspects: The initial handshake is unavoidable whenever a new connection is turned on, that is, the browser needs to use http/1.x to establish a server connection each time. The encrypted data stored on the server will be more and more large, and the user will need to decode it when they read it. So how to deal

SSL/TLS AccessAlthough SSL/TLS is becoming more and more popular, its impact on performance should also be taken seriously. Its impact on performance is mainly reflected in two aspects: The initial handshake is unavoidable whenever a new connection is opened, which means that the browser needs to use http/1.x to establish a server connection every time. The encrypted data stored on the server becomes larger, and is decoded when the user reads it after being encrypted. So how d
