Question

If you have a request going to an application in the site  make sure you set maxRequestLength in the root web config   The maxRequestLength in the applications s web config appears to be ignored

User · Answer

If you can t update configuration files but control the code that handles file uploads use HttpContext Current Request GetBufferlessInputStream true     The true value for disableMaxRequestLength parameter tells the framework to ignore  configured request limits   For detailed description visit https   msdn microsoft com en-us library hh195568 v vs 110  aspx

It may be worth noting that you may want to limit this change to the URL you expect to be used for the upload rather then your entire site    lt location path  Documents Upload  gt     lt system web gt       lt  -- 50MB in kilobytes  default is 4096 or 4MB-- gt       lt httpRuntime maxRequestLength  51200    gt     lt  system web gt     lt system webServer gt       lt security gt         lt requestFiltering gt           lt  -- 50MB in bytes  default is 30000000 or approx  28 6102 Mb-- gt           lt requestLimits maxAllowedContentLength  52428800    gt          lt  requestFiltering gt       lt  security gt     lt  system webServer gt   lt  location gt

maxRequestLength  length in KB  Here as ex  I took 1024  1MB  maxAllowedContentLength  length in Bytes  should be same as your maxRequestLength  1048576 bytes   1MB     lt system web gt      lt httpRuntime maxRequestLength  1024  executionTimeout  3600    gt   lt  system web gt    lt system webServer gt      lt security gt         lt requestFiltering gt             lt requestLimits maxAllowedContentLength  1048576   gt         lt  requestFiltering gt      lt  security gt   lt  system webServer gt

I was dealing with same error and after spending time solved it by adding below lines in web config file  lt system web gt      lt httpRuntime targetFramework  quot 4 7 1 quot  maxRequestLength  quot 1048576 quot   gt   lt  system web gt   and   lt system webServer gt      lt security gt         lt requestFiltering gt           lt requestLimits maxAllowedContentLength  quot 1073741824 quot    gt         lt  requestFiltering gt       lt  security gt   lt  system webServer gt

I don t think it s been mentioned here  but to get this working  I had to supply both of these values in the web config   In system web   lt httpRuntime maxRequestLength  1048576  executionTimeout  3600    gt    And in system webServer   lt security gt       lt requestFiltering gt           lt requestLimits maxAllowedContentLength  1073741824    gt       lt  requestFiltering gt   lt  security gt    IMPORTANT   Both of these values must match  In this case  my max upload is 1024 megabytes   maxRequestLength has 1048576 KILOBYTES  and maxAllowedContentLength has 1073741824 BYTES   I know it s obvious  but it s easy to overlook

I had to edit the C  Windows System32 inetsrv config applicationHost config file and add  lt requestLimits maxAllowedContentLength  1073741824    gt  to the end of the       lt configuration gt       lt system webServer gt           lt security gt               lt requestFiltering gt    section   As per This Microsoft Support Article

If you are using IIS for hosting your application  then the default upload file size is 4MB  To increase it  please use this below section in your web config -   lt configuration gt       lt system web gt           lt httpRuntime maxRequestLength  1048576    gt       lt  system web gt   lt  configuration gt    For IIS7 and above  you also need to add the lines below     lt system webServer gt      lt security gt         lt requestFiltering gt            lt requestLimits maxAllowedContentLength  1073741824    gt         lt  requestFiltering gt      lt  security gt    lt  system webServer gt    Note     maxRequestLength is measured in kilobytes maxAllowedContentLength is measured in bytes    which is why the values differ in this config example   Both are equivalent to 1 GB
