title: Opening pdf urls with pyPdf
body: <p>How would I open a pdf from url instead of from the disk</p>
  
  <p>Something like</p>
  
  <pre><code>input1 = PdfFileReader(file("http://example.com/a.pdf", "rb"))
  </code></pre>
  
  <p>I want to open several files from web and download a merge of all the files.</p>
