Two requests from different threads with different urls in same httpclient instance

Question

I make two different 'GET' requests from two different threads at the same time. Will i have any conflicts if i will try to send at the same time but with different urls?

 static HttpClient client = new HttpClient();

 private void Thread1()
 {
   var result= await client.GetAsync("http://URL1");
 }

 private void Thread2()
 {
   var result= await client.GetAsync("http://URL2");
 }

Methods Thread1 and Thread2 will run at the same time. Will i have any problem? Or httpclient will handle both requests fine?

Hello,​

Welcome to our Microsoft Q&A platform!

No, you can use one HttpClent to 'GET' request several at the same time.

Here is an article from Henrik F. Nielsen about HttpClient where he says:

A single HttpClient can be used to send as many HTTP requests as you want concurrently so in many scenarios you can just create one HttpClient and then use that for >all your requests."

And since .NET 4.5 The following instance methods are thread safe, please refer to the following thread.

https://learn.microsoft.com/en-us/dotnet/api/system.net.http.httpclient?view=net-5.0#remarks

   CancelPendingRequests  
   DeleteAsync  
   GetAsync  
   GetByteArrayAsync  
   GetStreamAsync  
   GetStringAsync  
   PostAsync  
   PutAsync  
   SendAsync
