URL encoding problem

[Matthew Hegarty <ma...@diagonal-consulting.com>]

Hi
 
My problem in a nutshell is that I would like to encode a URL in exactly the
same way as InternetExplorer does - I just can't see how to do it!
 
In detail I have the following query:
 
uri = "action=query&text=%28%28MRH%29%29+&&DATABASEMATCH=Deposited_Papers
European_Materials&maxresults=1000&printfields=*/CONTENT-TYPE,*/UID&predict=
false&totalresults=true&combine=simple"

I call:
URIUtil.encodeQuery(uri, "UTF-8")

Which produces the output: 

action=query&text=%2528%2528MRH%2529%2529+&&DATABASEMATCH=Deposited_Papers%2
0European_Materials&maxresults=1000&printfields=*/CONTENT-TYPE,*/UID&predict
=false&totalresults=true&combine=simple
 

My problem is that the '%28' characters have been re-encoded as '%2528' and
this causes the Get request to fail for my purposes.
InternetExplorer and FireFox don't do this (they only encode the space
character).
How can I get HttpClient to encode in this same way so that my query is
successful.

Thanks
Matt

You can't. You have to present to HttpClient a URL that is either 
completely
escaped, or not at all. You can try whether the java.net.URL or 
java.net.URI
classes serve your purpose. You can alse try to decode the string first, 
then
re-encode it. That would prevent double encoding.

hope that helps,
  Roland
