How to implement the subscription to the server (p:port) and to remove the answers from the server after engagement. ♪ ♪
Like a connection to Battle.NET, I've been looking at the php connection codes, and logically think that if I get involved in the bowl, I'll get answers from the nick and password server, etc.

Like WinSock:
1. Open the juice. WSAStartup(...), inet_addr(...), socket(...)
2. Get on the server. connect(...)
3. Send a request. send(...)
4. Read the answer. recv(...)
5. Close the socket. WSACleanup(...)

You could implement a system of actors like akka http://akka.io/ The actors are programming units that use a query input queue (inbox), so if many requests arrive, they stay in the queue waiting to be attended and the actor handles them one in one, this way you will have a controlled flow against the database. If this is very slow, you can lift as many actors as you want until you take your limit to the base but in a controlled way.And if the base is already on its limit you can either expand the hardware or switch to a cluster structure to give it more capacity.

Using your example, the code would have the following changes:New class:TMyCustomDictionary = TObjectDictionary<integer, TCliente>; New use of the foDict object:foDict: TMyCustomDictionary; New create of foDict objectfoDict := TMyCustomDictionary.Create([doOwnsValues]); Made it, the button FreeList, no longer have

That's what it is. application/json (Stephen) https://ru.stackoverflow.com/a/262386/213987 , so I won't repeat the explanationsTry a connection like this:On c#, make a request:var req = (HttpWebRequest)WebRequest.CreateHttp("https://server/api/v1/method/"); req.Timeout = 1000 * 60 * 60; /* 1 hour */ req.Method = "POST"; req.ContentType = "application/json"; using (var s = req.GetRequestStream()) { var data = Encoding.UTF8.GetBytes(@"{ ""type"": ""demo"", ""name"": ""asdfasdf"" }"); s.Write(data, 0, data.Length); } using (var res = (HttpWebResponse)req.GetResponse()) { Console.WriteLine("{0} {1}", res.StatusCode, res.ContentType); //Console.WriteLine("{0} bytes:", res.ContentLength); using (var s = new StreamReader(res.GetResponseStream())) Console.WriteLine(s.ReadToEnd()); } You're practically the same, right? There's no special difference in making it async yes and Webclient in this case makes the same request as you.In real applications, of course, the line is formed with the help of Json.Net from the completed data class.In the PHP, you work like this:$handler->Execute(file_get_contents("php://input")); And in Execute something like:function Execute($postdata) { try{ $this->request = json_decode($postdata, true); Removed type and name I'll be visible. $this->request['type'] and $this->request['name']I've been working this connection a long time, really without base64, how much is this part of the question? I believe that when you go to the php://input, the problem will be solved by itself, but the answer can be clarified.

The type of technology used affects a little the ability to meet demand, but what matters even is the general architecture, is to know what you are doing. The least of the problems is what technology you're gonna use.Anyway, I don't know why Node is being considered a fast technology. Must have read a lot marketer around. Node is slow. Of course, you can do a lot with him, but you have to do a lot right to be fast, you have technologies that are much faster until you accept that something is not so good.Has a https://www.techempower.com/benchmarks/#section=data-r16&hw=ph&test=plaintext (it is worse when we talk about https://www.techempower.com/benchmarks/#section=data-r16&hw=ph&test=plaintext ). Until 11th. are almost 100% efficiency, including ASP.NET Core, he just loses to frameworks experimental. NodeJS appears in 59th. place with only 11% efficiency. So the decision the question asks must be the opposite of the proposal. Not that it's impossible to use Node, but it's one of the least viable options.IIS has improved a lot, but it will not be the best option in performance ever because its goal is to give diverse features and not performances. Even Nginx is not such a quick option. It is when compared to more complete servers, but it has its cost too.Either way, performance is not the most important and the decision of the best technology goes through extensive analysis and deep observation of the concrete case, and this can only be done by someone quite experienced and not biased, besides having all information in hand. But the most important thing is that the decision is not made upon false information.

First http://www.alexedwards.net/blog/golang-response-snippets In the google, I gave you a good example. Now that you're going to get back to the server, you'll be able to dissolve whatever you want.package main import ( "encoding/json" "net/http" ) type Profile struct { Name string Hobbies []string } func main() { http.HandleFunc("/", foo) http.ListenAndServe(":3000", nil) } func foo(w http.ResponseWriter, r *http.Request) { profile := Profile{"Alex", []string{"snowboarding", "programming"}} js, err := json.Marshal(profile) if err != nil { http.Error(w, err.Error(), http.StatusInternalServerError) return } w.Header().Set("Content-Type", "application/json") w.Write(js) }

(1) You don't have to worry about this, the server's gonna figure out how many streams and processes it takes for PHP. We just need to get the iron power to handle this.Part below is not true.(2) The violin php lives within the request and dies as soon as the request is completed, so it's not the best idea. If you want to make a demon on the php, you're gonna have to put in place a data exchange mechanism between your demon and the violin of Apache. There's a suspicion that you don't quite understand the way the browser is communicating with the server, so before these optimization decisions are made, I suggest that we take a more detailed look at the subject.

Cache-Control is a headline for hanging.Brauser can put a page on, and instead of asking for a server, take a bowl out of the bush. As a result, it's old data on the page.Cache-Control: no-cache, no-store The heading prohibits the hanging of pages Brauser♪HTTP proxy server can cut HTTP query headings, and and the browser can get a headline bruiser.Cache-Control) may be encapsulated (and again on the page with old data), so often (for critical data) add a specific url with a rib value ( fingerprint) fingerprintThis proxy won't cut.Stop writing jsp, it hurts follow-up support.

That's how it works correctly, maybe who's gonna need it:Procedure MeasureDisplayStringWidthAndHeight(Graphics: IGPGraphics; Text: String; Font: IGPFont; Var Width, Height: Extended); Var StringFormat: IGPStringFormat; R: TGPRectF; CharRanges: IGPCharacterRanges; CharRange: TGPCharacterRange; Regions: IGPRegions; Begin R.Initialize(0, 0, 1000, 1000); CharRanges := TGPArray<TGPCharacterRange>.Create(1); CharRange.Initialize(0, Length(Text)); CharRanges[0] := CharRange; StringFormat:= TGPStringFormat.Create; StringFormat.SetMeasurableCharacterRanges(CharRanges); Regions := Graphics.MeasureCharacterRanges(Text, Font, R, StringFormat); Regions[0].GetBounds(R, Graphics); Width:=R.Width; //ширина без отступов, если нужно с отступами R.Right Height:=R.Height; //можно так же получить из IGPFont End;

Set up a list comparing the tab indices with copies of windows.Take a method that will be responsible for: setting up a window, creating a cab, placing them on that list.Start windows using this method.At event onChange Check the current packaging index, check the list and pull the window.With window closure, it's harder. As the number of tabs will change, the list will have to run and the tab indexes exceed the closed packaging index.Then you'll understand that you're not comfortable with this, and you'll rewrite it pretty in the form of a few classes running a little final manager.In fact, TabSet is not the most convenient component for this task, but it's better to take something more interesting (with external designs, icons, baptism). And the VCLevsky MDI has many surprises.
