Getting 400 Bad Request SharePoint 2013 Rest API

Question

I am creating a web part that uses jQuery to do a REST API call to rename the SharePoint subsite. This works when using a custom button on EditForm.aspx on a list for example. It also works using Fiddler. However, I am getting an HTTP 400 Bad Request when trying to do this with a custom button in a web part.

Here is my code:

<script type="text/javascript" src="https://mysite.mysharepointsite.com/sites/vsdev/SiteAssets/jquery-1.7.2.min.js"></script>
<script type="text/javascript" src="https://mysite.mysharepointsite.com/sites/vsdev/SiteAssets/jquery.SPServices-2014.01.min.js"></script>

<script type="text/javascript">

function RenameSubsite()
{

$.ajax({
    url: "https://mysite.mysharepointsite.com/sites/vsdev/_api/web/",
    type: "POST",
    data: JSON.stringify({ '__metadata': { 'type': 'SP.Web' }, 'ServerRelativeUrl': "/vsdev2" }),
    headers: {
        "accept": "application/json;odata=verbose",
        "content-type": "application/json;odata=verbose",
        "content-length": "225",
        "X-HTTP-Method": "MERGE",
        "X-RequestDigest": $("#__REQUESTDIGEST").val(),
        "IF-MATCH": "*"
    },
    success: function (return_data, textStatus) {
        alert('Successfully Renamed the Site!');
        return;

    },

    error: function (xhr, textStatus, errorThrown) {
        alert('Error! - Status: ' + textStatus + ' Desc: ' + errorThrown);
        return;
    }
});

}
</script>

<p>
<input type="button" value="Rename Subsite to vsdev2" onclick="RenameSubsite()" />
</p>

Pretty straight forward REST API call...but it is not working from the web part..

UPDATE - Updating the 'Title' instead of the 'ServerRelativeUrl' works fine. I have tried all types of variations of the value to update the ServerRelativeUrl to as well.

It's impossible to update ServerRelativeUrl property. It's fixed once the site collection is created. You cannot manipulate this value via JSOM/CSOM.

The only way to change the URL of a site collection is to execute a server-side code: PowerShell (or other cmdlets like Copy-SPSite, Export-SPSite, Move-SPSite, etc.) or SSOM.
