A problem about URL parsing

[Zi Xuan Zhang <zh...@cn.ibm.com>]

Hi,

I am encoutering an exception when executing http request
(get/post/put/delete) when the URL includes '[' and ']'

org.apache.abdera.protocol.client.ClientException:
java.lang.IllegalArgumentException: Invalid uri
'http://localhost/dm/atom/library/[@PzzxLibrary/@RMain.nsf]/feed': escaped
absolute path not valid
      at
org.apache.abdera.protocol.client.CommonsClient.execute(CommonsClient.java:158)
      at org.apache.abdera.protocol.client.Client.post(Client.java:140)

I think this should be an valid URL, since I can get the correct response
from browser. Can you provide some information about this exception? Thanks
a lot!

Best regards,

The reasoning behind the error is that the characters [ and ] are
gen-delims and are not legal within IRI segments.  See section 2.2 of
RFC 3987 for more detail.  Those characters need to be percent-encoded.
 A quick test of firefox shows that the browser is, in fact,
percent-encoding those characters when it sends the request over the
wire.  e.g., I typed "http://www.snellspace.com/public/[test]" but it is
sent as http://www.snellspace.com/public/%5Btest%5D.
