Subject [jira] [Commented] (VFS-426) HTTP URL query string not part of cache key
Date Fri, 29 Jun 2012 20:17:43 GMT


Daniel Bergholm commented on VFS-426:

public void shouldResolveUrls() throws FileSystemException {
        String firstUrl = "";
        String secondUrl = "";

        FileSystemManager fileSystemManager = VFS.getManager();

        FileObject firstResult = fileSystemManager.resolveFile(firstUrl);
        assertEquals(firstUrl, firstResult.getURL().toExternalForm());

        FileObject secondResult = fileSystemManager.resolveFile(secondUrl);
        assertEquals(secondUrl, secondResult.getURL().toExternalForm()); // fails

> I am using commons-vfs amongst other things to download http files. When resolving different
URLs where only the query string differs, the default cache returns the wrong URL sometimes
(returning a previously accessed URL where only the query string differs).
> I think this is because the key property of URLFileName does not include the query string.
The {code:java}createURI(){code} method of URLFileName does include it, but when constructing
the key the {code:java}createURI(boolean useAbsolutePath, boolean usePassword){code} method
of AbstractFileName is used. This method only includes the path.
