I have an MVC project built in .Net Core 2.2 for Azure. The project runs locally, but when I upload it to Azure, I receive an error that I do not have permission to read this file or directory, and none of the pages are accessible. If I remove the
web.config file from the project, rebuild and upload again, it works. I can also attach an empty web.config and that also works.
With asp.net core, the web.config is for configuring the core module. The <location> and <system.web> Are not supported. You should only have <system.webServers> And use it to configure asp.net core module.

Azure MVC, adding web.config blocks access to website

THIS WORKS
THIS DOES NOT WORK
The path "EditPhrase/BuildPartial" is a POST action in the controller EditPhraseController.

Hi Terry,
As far as I know, just because you published to azure, the path has changed.
You need to change your path to a virtual path, like below:
For more details, you could refer to these links:

Location + Path in web.config not working in Azure

Thank you for your reply. Adding the location marker '~' did not help.
After the web.config is published to Azure, it changes to the following:
<?xml version="1.0" encoding="utf-8"?> <configuration> <location path="~/EditPhrase/BuildPartial"> <system.web> <httpRuntime maxUrlLength="300000" maxQueryStringLength="300000" maxRequestLength="100000" /> </system.web> <system.webServer> <security> <requestFiltering> <requestLimits maxQueryString="300000" maxUrl="100000" /> </requestFiltering> </security> <handlers> <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" /> </handlers> <aspNetCore processPath="dotnet" arguments=".\MvcApp.dll" stdoutLogEnabled="false" stdoutLogFile="\\?\%home%\LogFiles\stdout" hostingModel="InProcess" /> </system.webServer> </location> <location path="~/Flagged/UpdatePost"> <system.web> <httpRuntime maxUrlLength="300000" maxQueryStringLength="300000" maxRequestLength="100000" /> </system.web> <system.webServer> <security> <requestFiltering> <requestLimits maxQueryString="300000" maxUrl="100000" /> </requestFiltering> </security> </system.webServer> </location> </configuration>The publishing process has added new tags for "handlers" and "aspNetCore" to one of the locations, but no the other.

Thank you for the reply. Yes, the following works on both the development server and Azure:
<configuration> <system.webServer> <security> <requestFiltering> <requestLimits maxQueryString="300000" maxUrl="100000" /> </requestFiltering> </security> </system.webServer></configuration>
But it does apply to the whole website. Is it possible to limit the exceptional request limits to specific locations?

you would need to use asp.net core middleware to do this.
note: browsers (and proxy servers) often limit the url + query string length to 4k (2k if unicode), not sure why you are setting such high values.
