Hg clone: IIS server download limit

Question

I'm cloning a large mercurial repository ( > 10Gb) over http protocol from an IIS 8.5 Server. Although setting the maxAllowedContentLength and maxRequestLength to values over 2Gb, I'm still unable to clone the repo. It seems I'm hitting a download limitation size. The following exception is thrown:

bundle2-input-part: total payload size 64680856
bundle2-input-bundle: 0 parts total
transaction abort!
rollback completed
Abort: stream ended unexpectedly (got 0 bytes, expected 4)

My web.config file:

<system.webServer>
    <security>
        <requestFiltering>
            <requestLimits maxAllowedContentLength="4294967295" />
        </requestFiltering>
    </security>
<system.webServer>
<system.web>
    <sessionState timeout="240" />
    <httpRuntime executionTimeout="14400" maxRequestLength="2147483647" />
</system.web>

To my understanding adjusting the maxAllowedContentLength or maxRequestLength to values over 2Gb does not help because these settings are for ASP.NET, and not for IIS.

With incremental pulls you can get the entire repository on a changeset-by-changeset basis, thus reducing the amount of data transferred during each operation to an absolute minimum:

particularly check out this other question Is there any way to clone a repository from the web incrementally?

or perhaps more end-user solutions like this one https://github.com/tusharvjoshi/incremental-hg (which I don't endorse because I don't know it at all)
