Dunno how much use this will be but here's the php code which deals with the
file.

// save the file to a new location
        $uploaddir = "./tempuploads/";
        $uploadfile = $uploaddir . basename( $_FILES["file"]["tmp_name"] );
        move_uploaded_file( $_FILES["file"]["tmp_name"], $uploadfile );
       
       
       
       
   
        // load the file into the file structure
   
        $readFile = fopen( $uploadfile, "rb" );
        while ( feof( $readFile ) == false )
        {
            // read 2048 bytes at a time till we get to the end
            // NOTE this number is just one I choose
            // the number needs to be less then 8148 (I think)
            // because thats the maximum limit of the fread function in PHP
            $tempMem = $tempMem . fread( $readFile, 2048 );
        }
        fclose( $readFile );

I have aproximatively the same problem with WebClient.UploadFile method.
I've build a service that basically has to upload some files to a Http server.
Problem is if the file has 200MB for ex. it will eat up ~200MB of memory while uploading, and.....after upload is finished, memory remains aloccated.
Of course, you can imagine what happens if i try to upload several big files...

I've tried Dispose() - doesn't work
I've tried async call - doesn't work
