The Transport Layer Security (TLS) protocol

The Transport Layer Security (TLS) protocol is a pretty good encryption mechanism, it will take current computers very, very, very long time to decrypt TLS encryption. I am not sure if TLS encryption is vulnerable to quantum computing. Quantum computing is really-really fast, but it is at its infancy at this time.

TLS encryption is used in HTTPs pages.

TLS uses both asymmetric and symmetric encryption. Asymmetric encryption is used to pass secret key, used to encrypt the data, and symmetric encryption is used for the data.

Using symmetric encryption is much faster and less resource intensive, than asymmetric encryption.

Absolute and relative path in HTML pages

HTML documents can have relative or absolute links to other web pages. Relative links keeps a visitor on the same web site. Relative links are pointers to other web pages on the same web site. They just contain this page filename. Absolute links on other hand contain full path including protocol and domain name to access the page. Absolute links can point to the same web site or they can point to a different web site.

Errors

It is a good idea to send errors in production environment to error log. Errors may contain sensitive information. Even so errors maybe helpful to development team or to QA team, errors need to be suppressed in production environment for viewing by everyone. Errors are good way to troubleshoot an issue therefore only trusted people can have access to this information. If not a trusted person get an access to this information, this information maybe used against the company and for a personal benefit. What to do in a case when there are more servers than one? Even so it is possible to inspect the log files in a single server, however it is impossible to do so when there is more than one server is available and web traffic is redirected to a different server each time. Log aggregation is needed in this case. All of the logs will be send to a central location. Logs may contain sensitive information. Please consult your company lawyer of how long logs can be stored, because logs can be use...

goto PHP operator

goto operator will skip execution of code and continue execution of a code that follows a label to which goto operator points to. If code has many goto operators, than this code probably needs a revision. It is possible to write code that executes without goto operators.
