Description

The http provider classes don't test the header location before resolving a file. If the redirection is reported as invalid by commons-httpclient, then the HttpFileObject is not resolved. Here is how to fix it in all the http provider implementation classes.

int status = 0;//client.executeMethod(method);
try

{ status = client.executeMethod(method); System.out.println("method executed"); }

catch(Exception e){
System.out.println("Exception co");
try{
HostConfiguration config = client.getHostConfiguration();
Header header = method.getResponseHeader("Location");
System.out.println("Checking header");
if (header != null)

{ String redirectUrl = header.getValue(); config.setHost(new java.net.URL(redirectUrl).getHost(), config.getPort(), config.getProtocol()); client.setHostConfiguration(config); status = client.executeMethod(method); }

}
catch(Exception err)

{ throw new Exception(err); }

}
if ((status >= 300) && (status < 400)) {
try{
HostConfiguration config = client.getHostConfiguration();
Header header = method.getResponseHeader("Location");
if (header != null) { String redirectUrl = header.getValue(); method = new HeadMethod(); setupMethod(method); config.setHost(new java.net.URL(redirectUrl).getHost(), config.getPort(), config.getProtocol()); client.setHostConfiguration(config); status = client.executeMethod(method); }
}
catch(Exception err){ throw new Exception(err); }

}
method.releaseConnection();
if (status == HttpURLConnection.HTTP_OK)

{ return FileType.FILE; }

else if (status == HttpURLConnection.HTTP_NOT_FOUND

status == HttpURLConnection.HTTP_GONE) { return FileType.IMAGINARY; } else { throw new FileSystemException("vfs.provider.http/head.error", getName()); }
