title: Make a POST request while redirecting in flask
body: <p>I am working with flask.
  I am in a situation where I need to redirect a post request to another url preserving the request method i.e. "POST" method. When I redirected a "GET" request to another url which accepts "GET" request method is fine.
  Here is sample code with which I am trying the above..</p>
  
  <pre><code>@app.route('/start',methods=['POST'])
  def start():
      flask.redirect(flask.url_for('operation'))
  
  @app.route('/operation',methods=['POST'])
  def operation():
      return "My Response"
  </code></pre>
  
  <p>I want to make a "POST" request to "/start" url which internally also makes a "POST" request to "/operation" url.If I modify code as like this,</p>
  
  <pre><code>@app.route('/operation',methods=['GET'])
  def operation():
      return "My Response"
  </code></pre>
  
  <p>code works fine for "GET" request. But I want to be able to make POST request too.</p>
