: How do I increase the upload size in IIS? I can't upload more than 2 MB. I read that IIS' max. upload size is 4 (actually 4,2) GB and ASP.NET's is 2 GB. I really can't think of an alternative.

I can't upload more than 2 MB. I read that IIS' max. upload size is 4 (actually 4,2) GB and ASP.NET's is 2 GB.

I really can't think of an alternative. I could change the max. upload size in PHP but IIS isn't compatible with this causing the server not to accept uploads over 2 MB still.

But even if 4,2 GB can be uploaded, how can I configure that? I've tried everything but it just doesn't work!

I was also told that it can be increased via ASP.NET but I don't think it is to be honest. And even if, how?

What have I tried?

Change the web.config

I added this to the web.config file:

<configuration>
<system.web>
<httpRuntime maxRequestLength="xxx" />
</system.web>
</configuration>


Request filtering

I went to IIS -> servername -> Sites -> sitename -> Request Filtering -> Edit Feature Settings... and changed the Maximum allowed content length (Bytes) field there. Is that the one I need to change?



Change it in PHP

I changed the upload_max_filesize section:

; Maximum allowed size for uploaded files.
; php.net/upload-max-filesize upload_max_filesize = xxxM


to something else in the php.ini. It increased the limit in PHP but IIS must be compatible with that change, which it isn't, unfortunately.

Yes, I restarted IIS every time I made a change, but without effect unfortunately.

The error message I get all the time is:



I suggested to my 'client' to use Apache but he wants to use IIS, so switching is not really an option.
