From: Justin C on 21 Jun 2008 08:15 There is a web-site, pages generated by asp, from which I want to download a daily file. I have am registered with the site, and I pass my login details to wget thus: --post-data="Email=[removed]&Password=[removed]" The problem is, however, I get a "302 Object moved" message, and am then redirected to the registration page. I have tried using wget to connect to the site first, and save-cookies/keep-session-cookies before trying to login, but still no joy. I think the site is using some obfuscation to prevent automation - actually, it's more likely I'm not understanding how something in html is working. Here's the form they use: <FORM name="frmLogin" action="/Members.asp" method="POST"> Email: <INPUT name="Email" value="" size=8 maxlength=50 style="width:80;"> Password: <INPUT name="Password" value="" type="password" size=8 maxlength=20 style="width:80;"> <INPUT name="Login" type="image" src="/images/cmdLogin.gif" alt="Login" border="0"> <A href="/Members.asp"> <IMG src="/images/cmdRegister.gif" alt="Register" border="0"> </A> <A href="/Forgot.asp">Forgotten Password</A> </FORM> The first two inputs are simple enough, the third, name="Login", is clickable, but on hovering with a mouse there is no report in the status bar to where clicking will take me. In addition, clicking the register button links to the same page as the form does. I don't understand how the input "type=image" is causing the form to be submitted when it's not a link, nor a submit. I suppose, what I really want to know, is what is it submitting? Any help you can give solving this riddle will be gratefully received. Justin. -- Justin C, by the sea.

I suppose, what I really >want to know, is what is it submitting? It is a type of submit button - the browser will send two parameters: Login.x and Login.y, which are the mouse x and y coordinates respectively. It will probably suffice to add &Login.x=0&Login.y=0 to your post data. http://www.w3.org/TR/html401/interact/forms.html#h-17.4.1 Peter

The html is interesting, I shall have another read shortly and hope the info sticks. Justin. -- Justin C, by the sea. |
