This would allow clients to keep connections open between requests without having to do any special work on the server side to achieve it. However, one HTTP feature that has been a long-standing request from the community is to add the ability to send KeepAlive headers in the opposite direction. The HTTP/2 protocol supports persistent connections, a major improvement over HTTP/1.1. The KeepAlive header field is an experimental web technology whose use can be considered a workaround for the lack of persistent connections in HTTP/1.1 servers and has been obsoleted by more recent specifications. Here are the new updates of node js 19: The HTTP(S)/1.1 KeepAlive: Node.js has become the backend platform of choice for many developers because of its performance, speed, scalability, support for asynchronous I/O, ease of use, and rich ecosystem (npm). Node.js is open source and free for commercial use under the MIT License, but you can also purchase a commercial license if needed. ![]() It is built on Chrome’s V8 JavaScript engine. NodeJS is a JavaScript library for building fast and scalable network applications. The project also includes a package manager called npm, which manages dependencies like the transpilation of code during bundling. Node.js is an open-source software project that implements the V8 JavaScript runtime and other core libraries over HTTP connections. I plead ignorance since this is WCF and I am not sure what happens behind the applications are built upon the core JavaScript runtime and use it to implement server-side features such as asynchronous data streams, event-driven I/O, messaging, and more. I also am concerned I do not see any endpoints listed in the web.config file. So I am not sure what I need to do additionally or correct. And I created the profile for deployment and the deployment said success. I went according to the “publish” wizard from the “build” menu. Requested URL Physical Path C:\inetpub\wwwroot\WCFService1\ Locking is either by default (overrideModeDefault="Deny"), or set explicitly by a location tag with overrideMode="Deny" or the legacy allowOverride="false".Ĭonfig file \\?\C:\inetpub\wwwroot\WCFService1\web.config This happens when the section is locked at a parent level.

HTTP Error 500.19 - Internal Server Error The web service is deployed to IIS (it runs fine when I test which runs a temp iisexpress hosted session via debug menu) and then I try to access the URL for the service and get the following error: anyone can explain it nice like how to protect web api with HMAC hashing thanks Please help me to understand how to protect web api when using HMAC hasing against Replay attack. when client will send first request and then client may send second request after 10/15 minute later. what this area try to mean delayed for more than that it will have to be resent with a refreshed timestamp. We will generate hash based on secret key then how date comes to scene ? this points is not clear to me.Ģ) we introduce a requirement that no http request can be older than X minutes - if for any reason the message is delayed for more than that it will have to be resent with a refreshed timestamp. ![]() they saidġ) requests with different Date header values will have different signatures, thus attacker will not be able to modify the timestamp ![]() Suppose a attacker can capture the client request and send the same hash data to web api then how could we protect this ?įrom some where i found this below trick to protect it. if match then client will allow to call web api action. web api action will create a hash value of secret key and compare that value against client sent has value. client will create a has value of secret key and send it to web api always when calling web api action. they are saying client and server will share some secret key. I read few articles like how to secure web api.
