Hi Folks, Nowadays some websites let users to fill in some so-called verification code, and the tricky thing is that the CODE is delivered from server with an image. For example:
<img src="/jobsearch/captcha.jpg" name="CAPTCHA_IMAGE" border="1" / > <a href="#" onClick="changeSource();">Refresh Image</a> When click Refresh Image, the CODE on the image changes. I wonder: does the server really send a new image over to browser, or just send a hidden code over? Is it possible to parse out such hidden code? The other example is: <img src="/images/verify.png;jsessionid=ahZsBmwyLGuf" alt="Digital Signature Code" /> <input name="jsessionid" type="hidden" value="ahZsBmwyLGuf" /> I did a few REFRESH on browser, and noticed the CODE changed. But, when I viewed the HTML source code, the value "ahZsBmwyLGuf" remained the same. What is the trick around here? That is why I am wondering whether the server really keeps sending new images over, or just sending new hidden codes over. If the trick is just keep sending hidden codes over, there might be a chance of capturing the codes. Can somebody help me out? Thanks a lot!
