how to go back to the same page in data table after refreshing

To go back to the same page in a data table after refreshing in Go, you can use the http.Redirect function to redirect the user back to the desired page. Here are the steps to achieve this:

1. Import the necessary packages:

import (
    "net/http"
    "net/url"
)

1. Get the current URL and store it in a variable:

func handler(w http.ResponseWriter, r *http.Request) {
    currentURL := r.URL.Path
    // ...
}

1. Add a query parameter to the current URL to indicate the current page:

func handler(w http.ResponseWriter, r *http.Request) {
    currentPage := r.URL.Query().Get("page")
    newURL, err := url.Parse(currentURL)
    if err != nil {
        // Handle error
    }
    query := newURL.Query()
    query.Set("page", currentPage)
    newURL.RawQuery = query.Encode()
    // ...
}

1. Redirect the user back to the updated URL after refreshing:

func handler(w http.ResponseWriter, r *http.Request) {
    // ...
    http.Redirect(w, r, newURL.String(), http.StatusFound)
}

By following these steps, you can ensure that the user is redirected back to the same page in the data table after refreshing.
