Zend Framework: How to POST data to some external page (e.g. external payment gate) without using form?

Question

Hi,

I would like to have a user redirected to an external credit card gate. Of course I have to POST some user info to that gate, but I don't know how exactly can I do this.

I know that I could do this by generating a html form with hidden or read-only fields and have a user click "Submit" button. But this solution is not perfect, because all the form data could be easily changed using e.g. Firebug. I think you cannot do this using $this->_redirect(...). But maybe there is some other solution?

Many thanks for any tips or suggestions.

It is no more secure that using a redirect as the header data can be modified without too much of a problem. There are even Firefox plugins to do it.
