<input type=hidden>

Hi
If you have visited the AskJeeves site. then you must have noticed that it is a search engine and returns 
search results from multiple search engines.So if you ever view it's source you must have noticed that the search form is linked to a ASP file which generates an Active Server Page and includes many <Input type=hidden name=Meta> lines in the results page's source  code.Now is there any way to do it 
with Html without using Html,JavaScript,Vbscript?
Now we have to take the string written for searching and then put it in the <input type=hidden name=meta> lines.
Can we do it?
I don't thing so.Maybe you all have a solution.
Thanks,
Bye,
