+/**
+ * 
 Low level API for processing file uploads.
+ *
+ * 
 This class can be used to process data streams conforming to MIME
+ * 'multipart' format as defined in
+ * RFC 1867. Arbitrarily
+ * large amounts of data in the stream can be processed under constant
+ * memory usage.
+ *
+ * 
 The format of the stream is defined in the following way:

+ *
+ * 
+ * multipart-body := preamble 1*encapsulation close-delimiter epilogue

+ * encapsulation := delimiter body CRLF

+ * delimiter := "--" boundary CRLF

+ * close-delimiter := "--" boundary "--"

+ * preamble := <ignore>

+ * epilogue := <ignore>

+ * body := header-part CRLF body-part

+ * header-part := 1*header CRLF

+ * header := header-name ":" header-value

+ * header-name := <printable ascii characters except ":">

+ * header-value := <any ascii characters except CR & LF>

+ * body-data := <arbitrary data>

+ * 
+ *
+ * 
Note that body-data can contain another mulipart entity.  There
+ * is limited support for single pass processing of such nested
+ * streams.  The nested stream is required to have a
+ * boundary token of the same length as the parent stream (see {@link
+ * #setBoundary(byte[])}).
+ *
+ * 
Here is an example of usage of this class.

+ *
+ * 
+ *   try {
+ *     MultipartStream multipartStream = new MultipartStream(input, boundary);
+ *     boolean nextPart = multipartStream.skipPreamble();
+ *     OutputStream output;
+ *     while(nextPart) {
+ *       String header = multipartStream.readHeaders();
+ *       // process headers
+ *       // create some output stream
+ *       multipartStream.readBodyData(output);
+ *       nextPart = multipartStream.readBoundary();
+ *     }
+ *   } catch(MultipartStream.MalformedStreamException e) {
+ *     // the stream failed to follow required syntax
+ *   } catch(IOException e) {
+ *     // a read or write error occurred
+ *   }

 The default implementation of the
+ * {@link FileItem FileItem} interface.
+ *
+ * 
 After retrieving an instance of this class from a {@link
+ * DiskFileItemFactory} instance (see
+ * {@link org.apache.commons.fileupload2.servlet.ServletFileUpload
+ * #parseRequest(javax.servlet.http.HttpServletRequest)}), you may
+ * either request all contents of file at once using {@link #get()} or
+ * request an {@link InputStream InputStream} with
+ * {@link #getInputStream()} and process the file without attempting to load
+ * it into memory, which may come handy with large files.
+ *
+ * 
Temporary files, which are created for file items, should be
+ * deleted later on. The best way to do this is using a
+ * {@link org.apache.commons.io.FileCleaningTracker}, which you can set on the
+ * {@link DiskFileItemFactory}. However, if you do use such a tracker,
+ * then you must consider the following: Temporary files are automatically
+ * deleted as soon as they are no longer needed. (More precisely, when the
+ * corresponding instance of {@link File} is garbage collected.)
+ * This is done by the so-called reaper thread, which is started and stopped
+ * automatically by the {@link org.apache.commons.io.FileCleaningTracker} when
+ * there are files to be tracked.
+ * It might make sense to terminate that thread, for example, if
+ * your web application ends. See the section on "Resource cleanup"
+ * in the users guide of commons-fileupload.

+/**
+ * 
The default {@link FileItemFactory}
+ * implementation. This implementation creates
+ * {@link FileItem} instances which keep their
+ * content either in memory, for smaller items, or in a temporary file on disk,
+ * for larger items. The size threshold, above which content will be stored on
+ * disk, is configurable, as is the directory in which temporary files will be
+ * created.

+ *
+ * 
If not otherwise configured, the default configuration values are as
+ * follows:

+ * 
    
+ *   
  • Size threshold is 10KB.
    • 
+ *   
  • Repository is the system default temp directory, as returned by
+ *       {@code System.getProperty("java.io.tmpdir")}.
    • 
+ * 

+ * 

+ * NOTE: Files are created in the system default temp directory with
+ * predictable names. This means that a local attacker with write access to that
+ * directory can perform a TOUTOC attack to replace any uploaded file with a
+ * file of the attackers choice. The implications of this will depend on how the
+ * uploaded file is used but could be significant. When using this
+ * implementation in an environment with local, untrusted users,
+ * {@link #setRepository(File)} MUST be used to configure a repository location
+ * that is not publicly writable. In a Servlet container the location identified
+ * by the ServletContext attribute {@code javax.servlet.context.tempdir}
+ * may be used.
+ * 

+ *
+ * 
Temporary files, which are created for file items, should be
+ * deleted later on. The best way to do this is using a
+ * {@link FileCleaningTracker}, which you can set on the
+ * {@link DiskFileItemFactory}. However, if you do use such a tracker,
+ * then you must consider the following: Temporary files are automatically
+ * deleted as soon as they are no longer needed. (More precisely, when the
+ * corresponding instance of {@link File} is garbage collected.)
+ * This is done by the so-called reaper thread, which is started and stopped
+ * automatically by the {@link FileCleaningTracker} when there are files to be
+ * tracked.
+ * It might make sense to terminate that thread, for example, if
+ * your web application ends. See the section on "Resource cleanup"
+ * in the users guide of commons-fileupload.

+/**
+ * 

+ * A disk-based implementation of the
+ * {@link org.apache.commons.fileupload2.FileItem FileItem}
+ * interface. This implementation retains smaller items in memory, while
+ * writing larger ones to disk. The threshold between these two is
+ * configurable, as is the location of files that are written to disk.
+ * 

+ * 

+ * In typical usage, an instance of
+ * {@link org.apache.commons.fileupload2.disk.DiskFileItemFactory DiskFileItemFactory}
+ * would be created, configured, and then passed to a
+ * {@link org.apache.commons.fileupload2.FileUpload FileUpload}
+ * implementation such as
+ * {@link org.apache.commons.fileupload2.servlet.ServletFileUpload ServletFileUpload}
+ * or
+ * {@link org.apache.commons.fileupload2.portlet.PortletFileUpload PortletFileUpload}.
+ * 

+ * 

+ * The following code fragment demonstrates this usage.
+ * 

+ * 
+ *        DiskFileItemFactory factory = new DiskFileItemFactory();
+ *        // maximum size that will be stored in memory
+ *        factory.setSizeThreshold(4096);
+ *        // the location for saving data that is larger than getSizeThreshold()
+ *        factory.setRepository(new File("/tmp"));
+ *
+ *        ServletFileUpload upload = new ServletFileUpload(factory);
+ * 

+ * 

+ * Please see the FileUpload
+ * User Guide
+ * for further details and examples of how to use this package.

+/**
+ * 

+ * A component for handling HTML file uploads as specified by
+ * RFC 1867.
+ * This component provides support for uploads within both servlets (JSR 53)
+ * and portlets (JSR 168).
+ * 

+ * 

+ * While this package provides the generic functionality for file uploads,
+ * these classes are not typically used directly. Instead, normal usage
+ * involves one of the provided extensions of
+ * {@link org.apache.commons.fileupload2.FileUpload FileUpload} such as
+ * {@link org.apache.commons.fileupload2.servlet.ServletFileUpload ServletFileUpload}
+ * or
+ * {@link org.apache.commons.fileupload2.portlet.PortletFileUpload PortletFileUpload},
+ * together with a factory for
+ * {@link org.apache.commons.fileupload2.FileItem FileItem} instances,
+ * such as
+ * {@link org.apache.commons.fileupload2.disk.DiskFileItemFactory DiskFileItemFactory}.
+ * 

+ * 

+ * The following is a brief example of typical usage in a servlet, storing
+ * the uploaded files on disk.
+ * 

+ * 
public void doPost(HttpServletRequest req, HttpServletResponse res) {
+ *   DiskFileItemFactory factory = new DiskFileItemFactory();
+ *   // maximum size that will be stored in memory
+ *   factory.setSizeThreshold(4096);
+ *   // the location for saving data that is larger than getSizeThreshold()
+ *   factory.setRepository(new File("/tmp"));
+ *
+ *   ServletFileUpload upload = new ServletFileUpload(factory);
+ *   // maximum size before a FileUploadException will be thrown
+ *   upload.setSizeMax(1000000);
+ *
+ *   List fileItems = upload.parseRequest(req);
+ *   // assume we know there are two files. The first file is a small
+ *   // text file, the second is unknown and is written to a file on
+ *   // the server
+ *   Iterator i = fileItems.iterator();
+ *   String comment = ((FileItem)i.next()).getString();
+ *   FileItem fi = (FileItem)i.next();
+ *   // file name on the client
+ *   String fileName = fi.getName();
+ *   // save comment and file name to database
+ *   ...
+ *   // write the file
+ *   fi.write(new File("/www/uploads/", fileName));
+ * }
+ * 

+ * 

+ * In the example above, the first file is loaded into memory as a
+ * {@code String}. Before calling the {@code getString} method,
+ * the data may have been in memory or on disk depending on its size. The
+ * second file we assume it will be large and therefore never explicitly
+ * load it into memory, though if it is less than 4096 bytes it will be
+ * in memory before it is written to its final location. When writing to
+ * the final location, if the data is larger than the threshold, an attempt
+ * is made to rename the temporary file to the given location.  If it cannot
+ * be renamed, it is streamed to the new location.
+ * 

+ * 

+ * Please see the FileUpload
+ * User Guide
+ * for further details and examples of how to use this package.
+ *

-/**
- * A simple handler that serves incoming HTTP requests to send their respective
- * HTTP responses.  It also implements {@code 'If-Modified-Since'} header to
- * take advantage of browser cache, as described in
- * RFC 2616.
- *
- * 
How Browser Caching Works

- *
- * Web browser caching works with HTTP headers as illustrated by the following
- * sample:
- * 
    
- * 
  1. Request #1 returns the content of {@code /file1.txt}.
    2. 
- * 
  2. Contents of {@code /file1.txt} is cached by the browser.
    3. 
- * 
  3. Request #2 for {@code /file1.txt} does return the contents of the
- *     file again. Rather, a 304 Not Modified is returned. This tells the
- *     browser to use the contents stored in its cache.
    4. 
- * 
  4. The server knows the file has not been modified because the
- *     {@code If-Modified-Since} date is the same as the file's last
- *     modified date.
    5. 
- * 

- *
- * 
- * Request #1 Headers
- * ===================
- * GET /file1.txt HTTP/1.1
- *
- * Response #1 Headers
- * ===================
- * HTTP/1.1 200 OK
- * Date:               Tue, 01 Mar 2011 22:44:26 GMT
- * Last-Modified:      Wed, 30 Jun 2010 21:36:48 GMT
- * Expires:            Tue, 01 Mar 2012 22:44:26 GMT
- * Cache-Control:      private, max-age=31536000
- *
- * Request #2 Headers
- * ===================
- * GET /file1.txt HTTP/1.1
- * If-Modified-Since:  Wed, 30 Jun 2010 21:36:48 GMT
- *
- * Response #2 Headers
- * ===================
- * HTTP/1.1 304 Not Modified
- * Date:               Tue, 01 Mar 2011 22:44:28 GMT
