If you look at the source of that website you'll see they have a
decently complex bit of JavaScript which parses your inputs into a
proper URL for their server. A simple HTML POST using curl won't cut
it, you have to replicate what the web page does and then have curl
make the request.
In other words, it's not curl - it's whoever scripted the web page
using JavaScript. The second example you gave goes uses the JavaScript
on the web page and just fills in the fields and has it do the parsing
for you. Or so I believe, I never payed that much attention to
JavaScript.

I am not an expert on curl, but I have been unable to make it work on
some sites, such as
http://zip4.usps.com/zip4/zip4_responseA.jsp?
set theAddress to "1600 Pennsylvania Ave NW"
set theZip to "20500"
set theCurlCommand to "Curl -d Selection=1 -d address1=" & theAddress
& " -d address2= -d city= -d state= -d zipcode=" & theZip & "
http://zip4.usps.com/zip4/zip4_responseA.jsp";
set theZipCodeInformation to do shell script theCurlCommand
results in:
"<HTML><HEAD><TITLE>Server Error</TITLE></HEAD>
<BODY><H1>Server Error</H1>
This server has encountered an internal error which prevents it from
fulfilling your request. The most likely cause is a misconfiguration.
Please ask the administrator to look for messages in the server's
error log.
</BODY></HTML>"
replacing the spaces in theAddress with " " produces the same error
as does replacing them with "+"
The following, using Safari, works:
set theAddress to "1600 Pennsylvania Ave NW"
set theZip to "20500"
tell application "Safari"
make new document at beginning of documents
set URL of result to "http://www.usps.com/zip4/welcome.htm";
end tell
delay 3
set theJS to "document.forms.frmzip.address1.value=\"" & theAddress &
"\";
document.forms.frmzip.zipcode.value=" & theZip & ";
document.forms.frmzip.address.value=document.forms.frmzip.address1.valu
e;"
set theSubmitter to "document.forms.frmzip.submit();"
tell application "Safari"
set x to (do JavaScript theJS in document 1)
set z to (do JavaScript theSubmitter in document 1)
delay 3
set theContents to source of document 1.0
end tell
So, it would appear that scripting the browser might be more effective
for some tasks.

does anybody know of some information about what you

netscape 4 and mozilla controllable with apple script? can
i make them open special urls via applescript? can figure
out if a page is fully loaded?
Of course, any discussion of scripting browsers would be incomplete
without mentioning 'do shell script "curl ..."', which is far more
effective for many Web tasks -- it just returns the page source as a
string. (Requires Mac OS X, naturally.)
