Sometimes we need to limit the size of the file being upload to a website, in this case is on Sage CRM 7.0. We can set it in the “web.config” file in the root folder of the website. We need to add “requestLimits” element with “maxAllowedContentLength” parameter. We can put it like below in the “web.config” file.
<system.webSecurity> <security> <requestFiltering> <requestLimits maxAllowedContentLength="68157440" /> </requestFiltering> </security> </system.webSecurity>
Check the IIS website for the complete list and detail explanation.
