## Aurigma Image Uploader 7.0.15

# Configuring ASP.NET

- Collapse All Sections
- Language Filter ( all languages )

Typically, default server configuration does not allow uploading files with Image Uploader. This topic describes how to configure a server you are going to deploy Image Uploader on properly.

## Configuring Permissions

The folder where you are going to save files should have modify permissions. Depending on your operating system it can be set in one of the following ways:

- On Windows NT/2000/XP you should grant the modify permission to the Internet guest user (IUSR_<machinename>).
- On Windows 2003 Server you should grant the modify permission to the NETWORK SERVICE group.
- On Windows Vista/2008 Server/7 you should grant the modify permission to the account your site application pool is running under, Network Service by default.

## Configuring Maximum POST Request Length

Usually limitation for maximum POST request length is specified to reduce the risk of DoS attacks. If the request size exceeds a specific value, it is considered malicious and the upload would be broken.

If you are going to upload files larger than the default limitation, increase the latter as you need.

For IIS 7:

1. Go to C:\Windows\System32\inetsrv\config\applicationHost.config and change

   ### XML

       <section name="requestFiltering" overrideModeDefault="Deny" />

   to:

   ### XML

       <section name="requestFiltering" overrideModeDefault="Allow" />

2. Add to your application's web.config the following sections:

   ### XML

       <system.webServer>
           <security>
               <requestFiltering>
                   <requestLimits maxAllowedContentLength ="2147482624" /> <!-- in bytes -->
               </requestFiltering>
           </security>
       </system.webServer>

   ### XML

       <system.web>
            <httpRuntime maxRequestLength="2097151"/> <!-- in kilobytes -->
       </system.web>

For IIS 6:

Add to your application's web.config the following section:

### XML

    <system.web>
        <httpRuntime maxRequestLength="2097151"/> <!-- in kilobytes -->
    </system.web>

If you have URLScan installed and still experience this problem, go through the following steps:

1. Open the UrlScan.ini file which is typically located at C:\Windows\system32\inetsrv\urlscan folder.
2. Set the MaxAllowedContentLength key to the desired value (in bytes).
3. Save changes and restart IIS.
