I will try to answer it a little bit more informally. Connection timeout – is a time period within which a connection between a client and a server must be established. Suppose that you navigate your browser (client) to some website (server). What happens is that your browser starts to listen for a response message … Read more
HTTP Head of line blocking Head of Line blocking in HTTP terms is often referring to the fact that each browser/client has a limited number of connections to a server and doing a new request over one of those connections has to wait for the ones to complete before it can fire it off. The … Read more

The main semantic of HTTP has been retained in HTTP/2. This means that it still has HTTP methods such as GET, POST, etc., HTTP headers, and URIs to identify resources. What has changed in HTTP/2 with respect to HTTP/1.1 is the way the HTTP semantic (e.g. “I want to PUT resource /foo on host example.com“) … Read more
The Access-Control-Allow-Methods header indicates which HTTP methods are allowed on a particular endpoint for cross-origin requests. If you allow all HTTP methods, then its ok to set the value to something like Access-Control-Allow-Methods: GET, PUT, POST, DELETE, HEAD. However, if you want to limit the endpoint to only a few methods, you should only include … Read more
http.StripPrefix() forwards the handling of the request to one you specify as its parameter, but before that it modifies the request URL by stripping off the specified prefix. So for example in your case if the browser (or an HTTP client) requests the resource: /static/example.txt StripPrefix will cut the /static/ and forward the modified request … Read more
It’s not much about speed. There are plenty of cases where POST is more applicable. For example, search engines will index GET URLs and browsers can bookmark them and make them show up in history. As a result, if you take actions like modifying a DB based on a GET request, it might be harmful … Read more
First, this is not an error. The 3xx denotes a redirection. The real errors are 4xx (client error) and 5xx (server error). If a client gets a 304 Not Modified, then it’s the client’s responsibility to display the resouce in question from its own cache. In general, the proxy shouldn’t worry about this. It’s just … Read more
A recent post by Jacques Mattheij, referencing your very question, claims that although HTTP was designed as a synchronous protocol, the implementation was not. In practise the browser (he doesn’t specify which exactly) accepts answers to requests have not been sent yet. On the other hand, if you are looking to something less hacky, you … Read more
In PowerShell v3, have a look at the Invoke-WebRequest and Invoke-RestMethod e.g.: $msg = Read-Host -Prompt “Enter message” $encmsg = [System.Web.HttpUtility]::UrlEncode($msg) Invoke-WebRequest -Uri “http://smsserver/SNSManager/msgSend.jsp?uid&to=smartsms:*+001XXXXXX&msg=$encmsg&encoding=windows-1255”
