Http Post Plugin - Remote Server Returned An Error: (500)

[APTS 3]

I am trying to use Aymen's HTTP Post plugin but I cannot seem to grab the document text.  I am getting an error:

The remote server returned an error: (500) Internal Server Error.

The first part of my code navigates to the desired site, then I enter login information and search parameters.  The next step is to loop through the search results, which I am trying to do using the $http get command of the HTTP post plugin.  Here is my code:

 

clear all data
navigate("http://targetsite.com/?page=login","Wait")
type text(<username field>,"username","Standard")
type text(<password field>,"password","Standard")
click(<login button>,"Left Click","No")
wait(1)
click(<innertext="Start Search">,"Left Click","No")
wait(1)
change dropdown(<name="startyr">,2015)
wait(1)
click(<value="search">,"Left Click","No")
wait(1)
set(#position,0,"Global")
loop(3) {
    set(#x,$plugin function("HTTP post.dll", "$http get", targetsite.com/?page=details&skip={#position}", "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2228.0 Safari/537.36", "", "", ""),"Global")
    Scrape_Data()
    plugin command("HTTP post.dll", "http file download", targetsite.com/?page=details&skip={#position}", "C:\\myfolder\\{#myfilename}.html", "")
    increment(#position)
}

 

Can someone explain why I am getting the Internal Server Error?  Thanks.

 

One final related question:  I recently updated to version 5.8.5 of the software and I am glad that I did.  Pages now load incredibly fast, and overall this version seems more stable.  One of the new features is the ability to do "headless browsing".  What is the difference between headless browsing, and the `$http get` command from Ayment's HTTP Post plugin?  Are they both essentially the same thing?  Thanks again.

loop(1) {
    set(#x,$plugin function("HTTP post.dll", "$http get", "http://targetsite.com/?page=details&skip={#position}", $plugin function("HTTP post.dll", "$http useragent string", "Firefox 27.0 Win7 64-bit"), "", "", ""),"Global")
    plugin command("HTTP post.dll", "http file download", "http://targetsite.com/?page=details&skip={#position}", "C:\\\\myfolder\\\\{#myfilename}.html", "")
    increment(#position)
}

Thanks for trying addy196, but I still get the Internal Server Error using your code.

The browser and the http plugin doesn't use the same cookies container , so you need to login with the http plugin in order to access a page behind a login!
