I'm trying to access an xml file over http. The address is similar to:
http://localhost/app/config/file.xml
When pasting this in a browser the xml is displayed as expected. In my software I am using:
MSXML2::IXMLHTTPRequestPtr rp;
...
rp->open( "GET" , "http://localhost/app/config/file.xml" );
and getting the following response:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>IIS 7.0 Detailed Error - 400.0 - Bad Request</title>
<style type="text/css">
<!
Does anyone have any ideas what might be happening?
EDIT: more info, when trying to connect to another server in the office (which I can connect to fine using a browser) I'm getting a response of "Bad Request" and no more.
The function making the call is:
#import "msxml3.dll"
BOOL HTTPGet(LPCTSTR URL, CString &Response, long Timeout, BOOL ForceNoCache )
{
BOOL ret = FALSE;
MSXML2::IXMLHTTPRequestPtr rp;
//MSXML2::IServerXMLHTTPRequestPtr rp;
try
{
HRESULT hr = rp.CreateInstance( __uuidof( MSXML2::XMLHTTP ) );
//HRESULT hr = rp.CreateInstance( __uuidof( MSXML2::ServerXMLHTTP30 ) );
if( SUCCEEDED( hr ) )
{
rp->open( "GET" , URL );
if( ForceNoCache )
rp->setRequestHeader( "If-Modified-Since", "Sat, 1 Jan 1970 00:00:00 GMT" );
rp->send();
for( DWORD tc = GetTickCount() ; rp->readyState != 4 && GetTickCount() < tc + Timeout ; )
{
Sleep( 50 );
//WaitMessage();
for( MSG msg ; PeekMessage( &msg, 0, 0, 0, PM_REMOVE ) ; )
{
TranslateMessage( &msg );
DispatchMessage( &msg );
}
}
if( rp->readyState == 4 )
{
Response = (LPCSTR)rp->responseText;
ret = TRUE;
}
else
Response = "Timed out";
}
}
catch( CException &e )
{
char err[ 2048 ];
if( e.GetErrorMessage( err , sizeof( err ) ) )
Response = err;
else
Response = "Unhandled exception";
}
catch( _com_error &e )
{
Response = e.ErrorMessage();
}
catch( ... )
{
Response = "Unhandled exception";
}
return ret;
}
EDIT2: The function works correctly when ForceNocache set to false making the If-Modified-Since header the problem... I'll start up a new question if I can't work out why this isn't liked (by iis 7) but if someone here can point me in the right direction it will save some noise.
Thanks for all your help.
