Refused to get "Unsafe Header - Location" while getting response header in item service

Hi,

     
        Today i'm going to share my issue experience while creating item using item service in sitecore.services.client.

REST API is one of the key features in sitecore.

Sitecore provides two ways to use REST API
.
1. Item Service
2. Entitiy Service

If you want more explanation please refer the below url

Issue: 
         
I'm trying to create an item using ItemService in Sitecore.Services.Client.

Item creation is working fine and response looks like this:

201 (Created).

Location: /item/0727f965-2338-43cc-bd88-5071ad3f7a12?database=master

My need is to get this location in the response header.

During that I'm facing this issue:

refused to get unsafe header "Location" Error

my code sample:

 request.setRequestHeader('Access-Control-Expose-Headers', 'Location');
            request.onreadystatechange = function () {
                if (this.readyState == 4) {
                    console.log(this.status); 
                    console.log(this.getResponseHeader('Location'));                                       
                }
            };

Solution:

I found the solution by adding the below line in web.config.

<httpProtocol>
      <customHeaders>
        <add name="Access-Control-Expose-Headers" value="*"/>
        <remove name="X-Powered-By" />
      </customHeaders>
 </httpProtocol>
