If we are using IIS 7 and .Net Framework 4, what will be the maximum value of maxRequestLength?
As per MSDN the default value is 4096 KB (4 MB).
UPDATE
As for the Maximum, since it is an int data type, then theoretically you can go up to 2,147,483,647. Also I wanted to make sure that you are aware that IIS 7 uses maxAllowedContentLength for specifying file upload size. By default it is set to 30000000 around 30MB and being an uint, it should theoretically allow a max of 4,294,967,295
