title: How to view the address of the POST request made when an HTML button is clicked?
body: <p>I am creating a project involving web scraping and web automation. I would like to first submit this form (<a href="http://rgsntl.rgs.cuhk.edu.hk/rws_prd_applx2/Public/tt_dsp_timetable.aspx" rel="nofollow noreferrer">http://rgsntl.rgs.cuhk.edu.hk/rws_prd_applx2/Public/tt_dsp_timetable.aspx</a>) then once you submit this form, I want to scrape the HTML page that comes up. The problem is I am not sure how to submit this form through a Go program.</p>
  
  <p>I was previously experimenting with Selenium to emulate a web browser but now I think there may be an easier way. I think that I should be able to make a POST request to the same address that the "submit" button of this form makes to and directly use the HTML page that is returned. The problem is that I cannot figure out how to get the address that the submit button makes a POST request to. I would like to ask if there is a way to monitor the address that the button makes a POST request to when it is clicked? Also if you see any flaws with my idea please do let me know. Thank you.</p>
