web scraping using python

Hi,

I'm using python Browser() to download html pages,
it's working for most of the sites,
it doesn't work for: http://www.hashulchan.co.il/?CategoryID=541&ArticleID=13120
I'm getting:

<html style="height:100%"><head><META NAME="ROBOTS" CONTENT="NOINDEX, NOFOLLOW"><meta name="format-detection" content="telephone=no"><meta name="viewport" content="initial-scale=1.0"><meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"></head><body style="margin:0px;height:100%"><iframe src="/_Incapsula_Resource?CWUDNSAI=9&xinfo=0-273981-0 0NNN RT(1427217058600 4) q(0 -1 -1 -1) r(0 -1) B12(4,315,0)&incident_id=253000020000650957-2911433792487456&edet=12&cinfo=04000000" frameborder=0 width="100%" height="100%" marginheight="0px" marginwidth="0px">Request unsuccessful. Incapsula incident ID: 253000020000650957-2911433792487456</iframe></body></html>

How can I download the page, is it some kind of protection?

Thanks.

Hi,

Thanks, I've no intention to scrape the all site or to harm it...

I'm using:
browser = Browser()
cookiejar = cookielib.LWPCookieJar()
browser.set_cookiejar(cookiejar)
browser.addheaders = [('User-agent', 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.99 Safari/537.36')]
browser.set_handle_gzip(True)
browser.set_handle_refresh(False)
browser.set_handle_redirect(True)
browser.set_handle_equiv(False)
browser.set_handle_robots(False)
html = browser.open(self._url).get_data()

Open in new window


and yet I'm getting sometime the posted result, and sometime:

<html>
