I tried the Class and it looks to be able to send POST data to a page
and request back the results. I am looking to actually goto the page
as if you had clicked on the link. I basically created an app that
sometimes tries to send data to a page that exceeds the max length
allowed in the URL. What are options for getting around that limit. I
could see using a form if I had just one link, but I have hundreds and
can't think of a way to just send the data from the link I click on if
I used a form.
I think the limit is in the browsers, something like 255 characters. So
I think you can submit a GET request using that class to an URL without
that limit.

There are also buffer limits in the web servers. For sending large
amounts of data to a script POST is the correct way.

You can do this with javascript.

Essentially use the onclick() stuff to poke the right data into a HIDDEN variable, and POST that to the form

So you have somewhere
<form method="post">
<INPUT type="hidden" name="postvariable1" id="p1" value="">

<div onclick="do_my_stuff("a very long string")";>Click here to go somewhere else
</div>
</form

and a javascript..
<script>
function do_my_stuff (p)
{
getElemntById[['p1']=p;
document.form[0].submit();
}
</script>

Syntax is guaranteed to be wrong, but thats the principle
.
