[SOLVED] How Shockwave player generates HTTP POST request?

How Shockwave player generates HTTP POST request?

I am intercepting HTTP request/response from an Adobe Shockwave-based web music player application using Chrome Dev tools. When I click the Play button on music player, HTTP request headers like following are raised:

POST /some_url HTTP/1.1
Host: something.com
Connection: keep-alive
Content-Length: 103
Origin: http://something.com
X-Requested-With: ShockwaveFlash/22
User-Agent: Mozilla
Content-Type: application/x-www-form-urlencoded
Accept: */*
Referer: http://something.com/player.swf
Accept-Encoding: gzip, deflate, br
Accept-Language: en-US,en;q=0.8

And Form data looks like following:

param1=561a0d9452069h76fhg46h67a599e8gy34nlj=
param2=something

Now, is there any way to know from where this param1=561a0d9452069h76fhg46h67a599e8gy34nlj= form data came from and how it is generated? If it's some kind of encrypted string or a token, how this is done?

Thank you for your answers

Solution

The HTTP request would have come from a URLRequest in ActionScript, which passes the data in key/value pairs. You could have a look at using SWFWire Inspector to decompile the code.
