golang http stop redirection

To stop HTTP redirection in Go (Golang), you can follow the steps below:

  1. Import the necessary packages: Begin by importing the required packages for handling HTTP requests and responses. In this case, you will need the "net/http" package.

  2. Create an HTTP client: Next, create an HTTP client using the "http.Client" struct. This client will be responsible for making HTTP requests and handling the responses.

  3. Disable redirection: By default, the HTTP client automatically follows redirects. To disable this behavior, you need to set the "CheckRedirect" field of the client's "Transport" struct to a custom function that returns an error.

  4. Define the custom redirect function: Create a function that matches the signature of "http.CheckRedirectFunc." This function will be called on each redirect to determine whether to follow the redirect or not.

  5. Return an error to stop redirection: Inside the custom redirect function, you can control the behavior of redirection. If you wish to stop the redirection, you can return the "http.ErrUseLastResponse" error. This error indicates that the client should not follow the redirect and instead use the last received response.

  6. Make HTTP requests: Finally, you can use the HTTP client to make the desired HTTP requests. The client will now respect the custom redirect function and stop redirection when the specified condition is met.

Note: It's important to handle any errors that may occur during the HTTP requests and response handling process to ensure proper error handling in your application.

These steps should help you stop HTTP redirection in Go (Golang) and provide you with more control over the redirection behavior in your application.
