1.The default value for this config setting is 4096 in KB, that means 4MB, like you can see in
MSDN[
^]
2.So you have to increase this value, in your config file, to maximum allowed, but you should have a look also in the IIS constrains:
requestLimits element for requestFiltering in IIS[
^]
3.The maximum value for
maxRequestLength
is
2147483647
in
KB
that means
2TB
(Terra Bytes) and not
2MB
. The problem is that this setting is affected from IIS settings like I said in my 2nd point, so you should increase also some IIS related configurations.
