# Configuring HTML5/Flash Uploader PHP

Supported technologies: ![Adobe Flash](https://www.aurigma.com/docs/us8/icons/flash.png)![HTML 5](https://www.aurigma.com/docs/us8/icons/html5.png)
 
Normally, default server configuration does not allow to upload files with HTML5/Flash Uploader. This topic describes how to configure a server you are going to deploy HTML5/Flash 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.
- For \*NIX systems you should specify *read* and *write* permissions.

## Configuring Maximum POST Request Length
 
Usually, a 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.
 
### Editing PHP Configuration Files
 
To increase the limit of the maximum upload size, you should edit your PHP configuration files:
 
1. Open the `php.ini` file. You can find it:

    - on **Linux** in `/etc/php.ini`
    - on **Windows** in `c:\windows\php.ini`
2. Set the required limits:
 ```
    post_max_size = 100MB
    upload_max_filesize = 100MB
    ```
3. Additionally, you can set the following parameters:

    - `max_file_uploads`, the maximum number of files allowed to be uploaded simultaneously.
    - `memory_limit`, the maximum amount of memory in bytes that a script is allowed to allocate.
    - `upload_tmp_dir`, the temporary directory used for storing files when doing file upload.
    - `max_execution_time`,the maximum time in seconds a script is allowed to run before it is terminated by the parser.
    - `magic_quotes_gpc`, should be `off`, otherwise files sent by Flash uploader may be corrupted.

To make sure that new settings are applied, use the **phpinfo()** function which outputs information about the current state of PHP.
 ```
<?php phpinfo();
?>
``` 
### Configuring Apache Web Server
 
If you use the Apache web server, you should also edit the `php.conf` file:
 
1. Open the `php.conf` file. You can find it:

    - on **Linux** in `/etc/httpd/conf.d/php.conf`
    - on **Windows** in `<Apache installation folder>\conf\php.conf`
2. Change the `LimitRequestBody` parameter according to the `post_max_size` value, e.g.:
 
    `LimitRequestBody 104857600`

Do not forget to restart your server after modifying its configuration.
 
### Configuring IIS Web Server
 
If you use the IIS web server, you should follow one of the next configurations.
 
#### IIS 7 Configuration
 
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>
    ```

#### IIS 6 Configuration
 
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.

Do not forget to restart your server after modifying its configuration.
