simulating/calling javascript functions programmatically

[YR]

Hello,

I am tasked to write an application for a travel agency, that should be able to get a price for airline tickets from airline's website. Generally, airlines don't provide any web services for this, so I am sort of forced to simulate all the clicks/list boxes selection that a regular user would make. Most of those buttons have a java script associated with them, so as soon as a button's clicked -- java script runs.

So, here is the question: what's the best way to implement a call to a javascript? Would I use ASP.NET platform, since it has these HttpRequest / Response objects? What would I put in my HttpRequest?

For instance, if a web page http://www.mysite.com/page.cgi has a java script that looks something like this:

function submit_SomeForm()
{
document.SomeForm.A.value = "A"
document.SomeForm.B.value = "B"
document.SomeForm.C.value = "C"

document.SomeForm.submit()
}

What would be a code snippet that would setup SomeForm document with all the values and submit it to the site?
Also, what tools would I use to see what the http string that goes from my browser to the site is like?

I understand that I am sort of asking for a lot but I appreciate any help -- I am a rookie at this and it's tough to ask the right question :)

I appreciate any help.

Sincerely,

Take a look at the WebRequest class which will allow you to do GET and
POST. For example, here is a sample doing a POST :
http://samples.gotdotnet.com/quickst...lientPOST.aspx

One of the first tools I would get for debugging would be something
like tcpTrace (see http://www.pocketsoap.com/tcptrace/). This easily
allows you to see all the traffic between yourself and a web site. You
can compare what your code is sending versus what the browser sends.
Even before debugging, it will show you a little bit about what
happens on the form.submit call.

I had a similar query (actually posted it just before yours) and found my
answer in the Page.RegisterClientScriptBlock method. It lets you add client
side Javascript to your page from within your server side ASP.NET code.
