Googlebot requests URLs with parameters that shouldn't exist

[stevelibby]

Hi
I have written a script this past weekend that helps me identify sql injection or pages that are trying to be accessed incorectly via web browser, this morning gbot is trying to pick up a url which contains extra parameters that dont exist. What i want to know is where does gbot get this url from? I know that it is not in my site as i have checked.
Also currently any mall form urls that come through i pass to a error page which is one i just created but is an server error one. Is this right or should i just chase it back to home page with a permant move?

An example of the query url url:
make=ALFA+ROMEO&menu=http://www.domainname.co.uk?make%3DVOLVO%26model%3DV70&model=GT

With my search today it appears "possibly" that the culprit maybe the following:
<form name="jump">
<p align="right">
<select name="menu" onChange="location=document.jump.menu.options[document.jump.menu.selectedIndex].value;" value="GO" style="padding-right: 25px" size="1">
<option>Choose County</option>
<option VALUE="http://www.DomainName.co.uk/Page.asp">Title</option>
</select></p>
</form>
But...this has nothing to do with the page itself or any links, so whats happenning?
