           Summary: XMLHttpRequest doesn't detect simple XML
           Product: konqueror
           Version: unspecified
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: kjs
        AssignedTo: konq-bugs kde org
        ReportedBy: ikrabbe.ask web de


Version:            (using KDE 3.5.8)
Installed from:    Gentoo Packages
Compiler:          gcc 4.1.1 32bit
OS:                Linux

I just wondered why recently my JavaScript code broke down using the requestXML \
member of XMLHttpRequest objects in very simple objects.

I now cross checked the behaviour by storing the Applications answer in a file and \
use that file as the answer xml object, which is detected fine.

The complete protocol data failing is (rebuilding the request with wget):

HTTP/1.1 200 OK
Date: Tue, 13 May 2008 13:05:59 GMT
Server: Apache
Content-Encoding: identity, identity
Cache-control: no-cache=set-cookie, no-cache
Set-cookie: tr_session1=%3Csession key=%22LOGIN:0000000048218D5D.A079%22%3E%3Cchanged \
when=%220000000048299238.2AF4%22 by=%22172.17.9.68:80%22/%3E%3C/session%3E; \
                Version=1; path=/

<?xml version="1.0" encoding="utf-8"?>
<login><status>1</status><message>ok</message><code>0</code><flags>132</flags><name>iktest11</name></login>




The valid data file answer is:

Connection: Keep-Alive
Content-Type: application/xml

<?xml version="1.0" encoding="utf-8"?>
<login><status>1</status><message>ok</message><code>0</code><flags>20</flags><name>ikrabbe</name></login>



Those two files don't really distinguish, but in some header fields.  Actually I \
copied the requestText result, where the requestXML member was undefined, to produce \
the file.

I will try to tune the headers with some cgi scripts next to find out, where the \
point really is, the XMLHttpRequest breaks down, but maybe one, familiar with kjs \
programming can imagine this problem from this bug report.

Actually this detection worked a few weeks ago, though I changed header fields a bit \
maybe the content-length is missing ?

In Firefox the same JS Code creates a valid requestXML Document from the same output.
