This is like submitting a form whose action is formAction, with two
fields named arg1 and arg2 with values in those fields of foo and bar.
don't forget to urlEncode if you have spaces or special characters
for more complex stuff, use /Developer/Examples/TCPMonitor. You
can capture the content of the form submission from a web browser
to see exactly how it is composed...

David,If you are interested send me a request "off-list" and I can provide you with example code that does exactly what your are trying to do.

Re: WOHTTPConnection & WORequest
Hi, David, Whew! If I understand you correctly, I'm not sure that's doable, and if it is, would require a greater network knowledge than my own. So, here's your requirement as I infer it: From a WebObjects application at www.xxx.com, you created and sent out a response to John Smith's browser with the following page: WOComponent Form Field1 Field2 Field3 Field4 ... SubmitButton If Field3 contains a domain name that John Smith entered into the form, say "www.yyy.com", you want the browser containing the above page to send the form values from that page as a standard HTTP request to www.yyy.com rather than back to your WOApp. You want some application there (a WO app?) to parse the request from John Smith's browser for its form values, and to generate a response that it will somehow smush into a pseudo-request containing the form values (or some transformation of them) which it will send directly to your WOApp at www.xxx.com. Your WOApp (the one which generated the original page to which John Smith is responding) will accept this pseudo-request from www.yyy.com, parse the form values therein and send its response back, not to www.yyy.com, but to John Smith's browser as if it were responding to the request the browser sent to www.yyy.com. I'm presuming that you have some control over the application at www.yyy.com, else how would you get it to take a request from John Smith's browser and return its response to your app? If this is a reasonable interpretation of your requirement, then, if it's doable at all, it's solution will require a grievous distortion of the standard HTTP network protocols on the part two web applications and some JavaScript hacking (in the page you originally sent out) on John Smith's web browser.

If you have the control over the two web apps to use this approach, it would work with network protocols appropriately rather than trying to violate them, and would probably provide you with a good deal more flexibility in your parsing and response. Additionally, down the line, when the requirements change, you can address the changed requirements immediately within the architecture rather than taking a long backwards step to figure out what the H*** was going on here between this browser and these two systems before even looking at the changes requested. And if you're not the one making the changes, you might save your own skin from the enmity of the programmer who follows you into this mine field.
