asp.net web api: IIS8 - (413) Request Entity Too Large
<p>I have <strong>asp.net web api</strong> application hosted in <strong>IIS</strong>. This app has 100mb in <code>&lt;httpRuntime maxRequestLength=...</code> and in <code>&lt;requestLimits maxAllowedContentLength=...</code>. But sometimes client gets <code>413 Request entity too large</code> in resoponse for quite small requests. I saw some fixes like "just change uploadreadaheadsize". But actually for me this solution is not clear. Why do I face this error when request limits are configured properly? <br/><strong>Update1:</strong> one more detail - this app uses client certificates authentication.<br/><strong>Update2</strong>: I found this <a href="https://technet.microsoft.com/en-us/library/cc737382(v=ws.10).aspx" rel="nofollow">https://technet.microsoft.com/en-us/library/cc737382(v=ws.10).aspx</a></p>
