Usually this implies future availability (e.g., a new feature of a web-service API). 502 Bad Gateway The server was acting as a gateway or proxy and received an invalid response from the upstream server. 503 Service Unavailable The server cannot handle the request (because it is overloaded or down for maintenance). Generally, this is a ...
The HTTP response status code 302 Found is a common way of performing URL redirection. The HTTP/1.0 specification (RFC 1945) initially defined this code, and gave it the description phrase "Moved Temporarily" rather than "Found". An HTTP response with this status code will additionally provide a URL in the header field Location.
302 Moved Temporarily The client should try at the address in the Contact field. If an Expires field is present, the client may cache the result for that period of time. [1]: §21.3.3 305 Use Proxy The Contact field details a proxy that must be used to access the requested destination. [1]: §21.3.4 380 Alternative Service
URL hijacking is an off-domain redirect technique [3] that exploited the nature of the search engine's handling for temporary redirects. If a temporary redirect is encountered, search engines have to decide whether they assign the ranking value to the URL that initializes the redirect or to the redirect target URL.
307 Temporary Redirect: Like 302, but guarantees that the method and the body will not be changed when the redirected request is made. 303 See Other : Used when the result of a POST or another non-idempotent request method is a resource that should be retrieved using a GET.
A simple memory pool module can allocate, for example, three pools at compile time with block sizes optimized for the application deploying the module. The application can allocate, access and free memory through the following interface: Allocate memory from the pools. The function will determine the pool where the required block fits in.
For version 1.1 of the HTTP protocol, the chunked transfer mechanism is considered to be always and anyway acceptable, even if not listed in the TE (transfer encoding) request header field, and when used with other transfer mechanisms, should always be applied last to the transferred data and never more than one time.
The low memory footprint (compared to other web servers), [5] small CPU load and speed optimizations [6] make lighttpd suitable for servers that are suffering load problems, or for serving static media separately from dynamic content. lighttpd is free and open-source software and is distributed under the BSD license.
