Yves Zoundi updated VFS-194:
----------------------------
Attachment: svn.diff
Here is a patch for the http provider. I added a check for URL redirections.
> Redirect of HTTP url using the header location
> ----------------------------------------------
>
> Key: VFS-194
> URL: https://issues.apache.org/jira/browse/VFS-194
> Project: Commons VFS
> Issue Type: Wish
> Environment: Windows XP/Linux/FreeBSD
> Reporter: Yves Zoundi

>
> 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);
>
> }
