title: How to change the amount of fields that can be posted in a form with IIS 7.5?
body: <p>We've hit a problem with some forms in the admin portion of our web app.  There are a handful of forms that contain a large number of fields (it can range anywhere from one input field to the hundreds).</p>
  
  <p>We've found that as these forms grow, there is a point where the server will throw 500 errors when a form is posted.</p>
  
  <p>After running a test, I was able to find that the server can handle forms with 100 fields in them; once 101 or more fields are used, we get the errors.</p>
  
  <p>We run Coldfusion, and we have determined that Coldfusion is not throwing this error.  We never see this error logged in Coldfusion, so we are assuming IIS is throwing an error even before it sends the request to the Coldfusion server.</p>
  
  <p>I'm assuming there is some setting in IIS 7.5 where we can up this limit.  I've searched on the web, but all I can find is how to raise the byte-size limits of this data, not any kind of limit on a number of fields that are allowed.</p>
  
  <p>So, am I right in assuming that this can be changed, and if so, how can it be done?</p>
