Erlang client for NTLM Authentication and NTLM Over HTTP ntlm_httpc:request(Method, Request, Credentials) -> {ok, Result} | {error, Reason} Replacement of httpc:request that supports NTLM authentication: The httpc module does not handle the "max" parameter of the "keep-alive" in the http protocol. The reason is that when a httpc_handle process is reach the max times of the "keep-alive:max", then server will close the connect, but httpc_manager also select this httpc_handler(because it is alive, and will append to its http request queue) to send http request, so the requester will receive the socket_closed_remotely.

When parsing a URI with an unknown scheme (that is, a scheme not found in the scheme defaults), a port number must be provided, otherwise the parsing fails. Tens of thousands of customers in 125 countries across six continents rely on us for their Erlang and call center staffing software.

Create links (if no links are available) Send / wait for return; stayerlang httpcIt is controlled by the following two parameters: timeout Time-out time for the request. Results are from Erlang 17.2.1. Running on Ubuntu 12.04 VM with 4 cores running on a 2013 MacBook Pro. httpc performs MUCH worse if {max_keepalive, infinity} is not set on the server. Running the tests. Make sure you have a high nofile limit, and enough sockets (on Ubuntu, sudo sysctl -w net.ipv4.ip_local_port_range="2048 65535").

From then on it was only a question of descending into the pits of the Erlang httpc module. Have I mentioned data transforms yet? It’s not fun having a database that speaks in json and an application that listens in Erlang.

Upon receiving this poll message, if not paused, it hits a url and saves the response to an ETS and fires off another erlang:send_after/3 to poll again after an appropriate interval. But I am having a hard time finding an example of posting data to an ssl endpoint via erlang. Does anybody know of a simple example that I am missing?

I found that HTTP client occasionally has a very long timeout. So I dig deep into the timeout of Erlang httpc. Httpc request time consuming.
NTLM Authentication, seemless Proxy authentication,seemeless Cookie support, e.t.c. Some time this year, i was working on a script behind an NTLM authenticated proxy and all Erlang HTTP Clients came to a stand still at this. Hence this is what was required curl \ 2020-05-25 3 HTTP Client 3.1 Configuration. The HTTP client default profile is started when the Inets application is started and is then available to all processes on that Erlang node. Other profiles can also be started at application startup, or profiles can be started and stopped dynamically in runtime. Erlang/OTP is a development and runtime environment for building distributed real-time high availability systems with short time to market requirements.

Please note that httpc normalizes input URIs before internal processing and special care shall be taken when the URI has percent ("%") characters. A percent serves as the indicator for percent-encoded octets and it must be percent-encoded as "%25" for that octet to be used as data within the URI. Hi I'm new to Erlang so please forgive my ignorance. I'm trying to stream data from a REST API using httpc, and although I have scoured the internet and the documentation I can't find a good example of how to do this, in particular how the "sync" and "receiver" options interoperate.
