This webpage has a redirect loop.

The webpage here has resulted in a lot of redirection. Clearing your cookies for this site or allowing third-party cookies may fix the problem. If not, this is probably a server configuration problem and there is no problem in your computer.

Here is a list for the DN Redirect Loops:

1 ) You are setting the middle of the trust level and using version 1.0.61025.0 of System.Web.Extensions. Complete and update trust level System for 3.5.0.0 in Web.config. Update all versions of the web (suppose that .NET 3.5 framework is installed).

Basic:

& lt; Trust level = "medium" ... ... ... system. Web. Extension, Version = 1.0.61025.0 ...

Updated:

  & lt; Trust level = "full" ... ... ... system. Web. Extension, version = 3.5.0.0 ...  

You should also check if a system. Web.Extensions.dll (version 1.0.61025.0) is in the / bin directory. If a compiled module is not dependent on this assembly version, you can remove the file. Otherwise, use assembly redirection in the web.config runtime section:

  & lt; Runtime & gt; & Lt; Assembly binding xmlns = "karash: schema-microsoft-com: asm.v1" & gt; & Lt; DependentAssembly & gt; & Lt; Assembly ID name = "System.Web.Extensions" publicKeyToken = "31bf3856ad364e35" /> & Lt; Compulsive Redirect Old Version = "1.0.0.0-1.1.0.0" Newverson = "3.5.0.0" /> & Lt; / DependentAssembly & gt; & Lt; DependentAssembly & gt; & Lt; Assembly ID name = "System.Web.Extensions.Design" publicKeyToken = "31bf3856ad364e35" /> & Lt; Compulsive Redirect Old Version = "1.0.0.0-1.1.0.0" Newverson = "3.5.0.0" /> & Lt; / DependentAssembly & gt; & Lt; / AssemblyBinding & gt; & Lt; / Order & gt;  

2) You have the following slash in the HTTPAlias ​​field in the PortAlias ​​table, delete it.
