HTTP POST request results in "ERROR 405: Method Not Allowed"

Question

I'm trying to do a simple HTTP POST on the following website:

https://oktap.tax.ok.gov/oktap/web/_/

(click on "Permits" in the bottom left hand side)

I simply want to post a number and get the results from the page returned. Looking at the page with chrome's web developer tools it looks like the POST goes to both

https://oktap.tax.ok.gov/oktap/web/_/Recalc
https://oktap.tax.ok.gov/oktap/web/_/EventOccurred

I'm not sure if it's one or the other, it looks like EventOccured takes a couple more parameters. However when I post to either one of them with the following code:

#!/usr/bin/env bash

wget --post-data="D0IHwpHb__0_0_Ful0QW=5&VIEW__=VS_PermitSearch&LASTFOCUSFIELD__=D0IHwpHb__0_0_Ful0QW&DOC_MODAL_ID__=0&EVENT__=D0IHwpHb__0_0_Ful0QW&DOC_ACTION__=false&TYPE__=1&CLOSECONFIRMED__=false&FAST_VERLAST__=9.CvUZWPROHiWR-EO6d9UAeHYv4m81" \
-U "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/29.0.1547 Safari/537.36" \
https://oktap.tax.ok.gov/oktap/web/_/EventOccurred

First I get 307 Temporary Redirect and then ERROR 405: Method Not Allowed.

I don't see how the a post is not allowed, when it's clearly being made from the browser just fine. Any Help?

Here's the headers:

As a developer for that company, I would not recommend looking up permits that way. For $150 per year you can get a file with this information.
