Does not send HTTP host header for remote dtd retrieval.

Description of problem:
As expected by any site using virtual hosting, a 404 or some other error will be
returned when requesting urls from these sites if a host header is not included.
When openjade does a remote retrieval to a hosted DTD, it does not send this
header, hence valid URL's to DTD's are erroniously flagged as invalid and
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Make an XML file, setting the doctype to a file on a virtual host.
2. Run openjade in any way, on that file.
Actual Results: openjade:stuff.xml:8:0:E: could not get "/whatever.xxxx" from
"www.virtualhost.com" (reason given was "Not Found")
Expected Results: Openjade should have retrieved the file from the virtual
host, and used it as a valid DTD. It may find errors in the DTD (if you just
used any old file for this test), but it should have at least retrieved the file.
This error occours on any version of openjade up to and including 1.3.1. Doing
a manual GET using no host header can reproduce the error returned by openjade.
Doing the GET with the host header will correctly return the file.

Apply "patch -p0 < host.patch" in openjade-1.3.1 directory.
This is fixed in openjade-1.3.1-10, which will show up in rawhide shortly. Thanks.
ran into problems with openjade behind transparent proxy on fedora
core 1 while building docbook documentation. A few remarks after
doing the homework :
a) the host patch is for OpenSP, not for openjade
b) there was an alternative patch put into OpenSP between 1.5pre5 and
c) Here's the changelog entry:

* NEWS, lib/URLStorage.cxx: Adapt SP patch from Liam Quinn that
adds a HTTP/1.0 Host header to HTTP requests. Necessary to fetch
DTDs specified in SYSTEM identifiers when the DTD resides on a
name-based "Virtual Host". Thanks to 'tbe'.
d) the patch is from Liam, whom I would trust with XML stuff (even
though he refuses to wear shoes :))
e) with this .host patch on top of this source code, it is sending out
bad headers with dual Host: fields
f) removal of the patch works fine again for me to any virtualhost
behind the transparent proxy.
So my suggestion is: ditch the patch, it's not correct for OpenSP >=
Fixed (again) in openjade-1.3.2-9. Thanks for investigating it.
