Dryscrape visit works only once in python

Question

I want visit page in loop.

Code is:

import dryscrape

dryscrape.start_xvfb()
sess = dryscrape.Session()
url = 'http://192.168.1.5';
loop = 1
while loop < 100000: 

    sess.set_header('user-agent', 'Mozilla/5.0 (Windows NT 6.4; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2225.0 Safari/537.36')
    sess.set_attribute('auto_load_images', False)
    sess.set_timeout(30)
    sess.visit(url)
    response = sess.body()
    print(response)
    print('loop:', loop)
    sess.reset()
    loop = loop + 1

According to output, page is visited only once time, I don't understand why? In 2., 3., .... there is no output:

('loop:', 1)
<!DOCTYPE html><html><head>
  <meta charset="utf-8">
  <title>Javascript scraping test</title>
</head>
<body>
  <p id="intro-text">Yay! Supports javascript</p>
  <script>
     document.getElementById('intro-text').innerHTML = 'Yay! Supports javascript';
  </script> 

</body></html>
('loop:', 2)

('loop:', 3)

('loop:', 4)

('loop:', 5)

('loop:', 6)

('loop:', 7)

Can you help me? Thank you.

Same problem with me i solve this with def try this

def fb(user,pwd)
 import dryscrape as d
 d.start_xvfb()
 Br = d.Session()
 #every time it creat a new session
 Br.visit('http://fb.com')
 Br.at_xpath('//*[@name = "email"]').set(user)
 Br.at_xpath('//*[@name = "pass"]').set(pwd)
 Br.at_xpath('//*[@name = "login"]').click()
 #......Now Do Something you want.....#

Then after making def now use this

 fb('my@account.com','password')

Then automatic login yourself user this command 100 time without error

After updating dryscrape and its dependencies to the latest version, it works fine now.

The versions are: dryscrape-1.0, lxml-4.1.1, webkit-server-1.0, xvfbwrapper-0.2.9

The code:

import dryscrape
dryscrape.start_xvfb()
sess = dryscrape.Session()
url = 'http://192.168.1.5/jsSupport.html';
loop = 1
while loop < 100000:

    sess.set_header('user-agent', 'Mozilla/5.0 (Windows NT 6.4; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2225.0 Safari/537.36')
    sess.set_attribute('auto_load_images', False)
    sess.set_timeout(30)
    sess.visit(url)
    response = sess.body()
    print(response)
    print('loop:', loop)
    sess.reset()
    loop = loop + 1

Output:

   'loop:' 1
   <!DOCTYPE html><html><head>
     <meta charset="utf-8">
     <title>Javascript scraping test</title>
   </head>
   <body>
     <p id="intro-text">Yay! Supports javascript</p>
     <script>
        document.getElementById('intro-text').innerHTML = 'Yay! Supports javascript';
     </script> 

   </body></html>
   'loop:' 2
   <!DOCTYPE html><html><head>
     <meta charset="utf-8">
     <title>Javascript scraping test</title>
   </head>
   <body>
     <p id="intro-text">Yay! Supports javascript</p>
     <script>
        document.getElementById('intro-text').innerHTML = 'Yay! Supports javascript';
     </script> 

   </body></html>
   'loop:' 3
   <!DOCTYPE html><html><head>
     <meta charset="utf-8">
     <title>Javascript scraping test</title>
   </head>
   <body>
     <p id="intro-text">Yay! Supports javascript</p>
     <script>
        document.getElementById('intro-text').innerHTML = 'Yay! Supports javascript';
     </script> 

   </body></html>

If you cant update the modules, or dont want to, a quick fix will be visiting another page at the end of the loop.

import dryscrape
dryscrape.start_xvfb()
sess = dryscrape.Session()
url = 'http://192.168.1.5/jsSupport.html';
otherurl = "http://192.168.1.5/test"
loop = 1
while loop < 100000:

    sess.set_header('user-agent', 'Mozilla/5.0 (Windows NT 6.4; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2225.0 Safari/537.36')
    sess.set_attribute('auto_load_images', False)
    sess.set_timeout(30)
    sess.visit(url)
    response = sess.body()
    print(response)
    print('loop:', loop)
    sess.reset()
    loop = loop + 1
    sess.visit(otherurl) #Visits the other url, so that when sess.visit(url) is called, it is forced to visit the page again.
