I am trying to mimic the use of a form:
http://www.usps.gov/ncsc/lookups/lookup_zip+4.html

I am using cURL ver. 7.7.1 on a WindowsME system. I invoke it with:
curl -K curl.txt http://www.usps.com/cgi-bin/zip4/zip4inq2

curl.txt is a text file with the following contents:
-o addout.html
-A "Mozilla/4.76 [en] (Win95; U)"
-e "http://www.usps.gov/ncsc/lookups/lookup_zip+4.html"
-d "City=&Zip%20Code=91104&Delivery%20Address=1800%20N%20Sierra%20Bonita%20Ave.&Firm=&State=&Submit=Process&Urbanization="

When I run this I get the response from the server that the State is incorrect,
but when I enter the data from the form, it works just fine. Putting in a valid
state does not fix the problem. Furthermore, when entered from the form, putting
in an invalid state does not cause problems if the Zip exists.

Any ideas? How am I being an idiot this time?

Thanks,
Dan
