Nintex Forms (on-prem) Web Request Control Internals
I would like to share my experience with Nintex Forms Web Request Control . It's a great Form control that everybody loves to use. However, I tried to do complex tasks based on that control and that is when it’s boundaries were revealed. In this post, I will explain what my objective was, how this control limited me and how I got around its limitations. Before that some nice things about this control Advantages This opens up the way to fetch the data from external data sources via HTTP protocol. Not only it provides the comfort of not having to write ajax code but also deals with the CORS issue that every ajax code has to face. How does it overcome CORS? Because it doesn’t request the external web service from the client/browser but rather requests the Nintex REST service ( /_vti_bin/NintexFormsServices/NfRestService.svc ) that is local to the current domain. Apparently, Nintex REST service does the talking with external web services behalf of the web request control. Amazing! Isn
