Module Http_client.Convenience

module Convenience: sig .. end

The environment variables http_proxy and no_proxy determine the proxy settings. http_proxy must be an http-URL that contains the proxy's name, its port, and optionally user and password. E.g. "http://eric:ericspassword@proxy:8080/". The variable no_proxy is a comma-separated list of hosts and domains for which no proxy must be used. E.g. "localhost, sun, moon, .intra.net"

There is a default behaviour for authentication. Both "basic" and "digest" methods are enabled. Two global variables, http_user and http_password set the user and password if the URL does not specify them. In the case that user and password are included in the URL, these values are always used.

There is a default error behaviour. If a request fails, it is automatically repeated. The variable http_trials specifies the number of times a request is submitted at most. Requests are not repeated if there is a HTTP return code that indicates a normal operating condition. POST and DELETE requests are never repeated.

Error codes are reported as Http_client.Http_error. Note that this is different than what the pipeline core does.

"https" support can be additionally configured via Https_client.

Thread safety

The Convenience module is fully thread-safe with the exception of the exported variables (http_trials, http_user, and http_password). Note that all threads share the same pipeline, and access to the pipeline is serialized. The latter simply means that it always works, but that threads may block each other (i.e. the program slows down if more than one thread wants to open http connections at the same time).
