SP configuration on IIS (ISAPI) and preservation of POST data

So we've been using Shibboleth for a while now and are very pleased.
We are running the SP (version 2.4.2) on IIS.
However we've noticed that when someone submits a form POST after their
session has timed out, when they are redirected back, the POST
parameters are missing and the page usually ends up in an error because
it was expecting a POST and instead its receiving a GET.
According to the docs
there are a few options that allow the SP to preserve the POST
parameters in a StorageService for replaying after authentication
(postData, postLimit, postTemplate, postExpire).
However, whenever I test this, I always get an error. The native.log
file has this message:
ERROR Shibboleth.ISAPI  isapi_shib: The request's Content-Length is not available to an ISAPI filter.
Is this a feature that isn't supported on the ISAPI version of the SP or
