title: How to download website when URL doesn't change after data addition
body: <p>I would like to download data from <a href="http://ec.europa.eu/taxation_customs/vies/" rel="nofollow noreferrer">http://ec.europa.eu/taxation_customs/vies/</a> site. Case is that when I enter data on it through program the URL doesn't change, so file saved on disc has a page same as the one which were opened from the begining without data.Maybe I don't know how to access this site after adding data? I'm new in Python and tried to look for solution but with no result so if there was such issue, please link me. Here's my code. I appreciate all responses:)</p>
  
  <pre><code>import requests
  import selenium
  import select as something
  from selenium import webdriver
  from selenium.webdriver.support.ui import Select
  import pdfkit
  
  url = "http://ec.europa.eu/taxation_customs/vies/?locale=pl"
  driver = webdriver.Chrome(executable_path ="C:\\Users\\Python\\Chromedriver.exe")
  
  
  driver.get("http://ec.europa.eu/taxation_customs/vies/")
  #wait = WebDriverWait(driver, 10)
  obj = Select(driver.find_element_by_id("countryCombobox"))
  obj = obj.select_by_index(1)
  
  vies_r = requests.get(url)
  vies_vat = driver.find_element_by_id("number")
  vies_vat.send_keys('U54799909')
  
  vies_verify = driver.find_element_by_id("submit")
  vies_verify.click()
  
  path_wkhtmltopdf = r'C:\Users\Python\wkhtmltox\wkhtmltox\bin\wkhtmltopdf.exe'
  config = pdfkit.configuration(wkhtmltopdf=path_wkhtmltopdf)
  print(driver.current_url)
  pdfkit.from_url(driver.current_url, "out.pdf", configuration=config)
  </code></pre>
