I have yet another problem with the filter and the media files which i
cannot figure out...

A media file is <EMBEDed into an html page. Bellow is a simple snippet
of OnPreprocHeaders code.

This is what happens:

* when I just pass the url to the media file through the filter AND
the url does not contain a query string after the file name (eg
/test.wma) it works fine with either 7 or 9 versions of WMP
* when I pass the url through the filter BUT the url contains query
string (eg /test.wma?v=12345) it fails when accessed via WMP7 (i am
getting 'The page cannot be displayed') but works when accessed from a
machine with WMP9 installed
* when I GetHeader("url") and then SetHeader("url") on
OnPreprocHeaders without modifying the url I can access it from WMP9
but not WMP7 (regardless whether a query string is present or not).
* this problem does not relate to html, gif, jpeg files

Is there some extra information that have to be passed in the header
for older WMPs? I tried to add
pCtxt->m_pFC->AddResponseHeaders(pCtxt->m_pFC, "Content-type =
application/x-mplayer2\r\n\r\n", 0); in OnPreprocHeaders but still the
same problem.

I would greatly appreciate any help or suggestions

many thanks

peter

PS using the code bellow I can access media files using WMP9 but not
WMP7



DWORD COvumFltrFilter::OnPreprocHeaders(CHttpFilterContext* pCtxt,
PHTTP_FILTER_PREPROC_HEADERS pHeaderInfo)
{
char pUrl[1024];
LPDWORD pBufLen = new DWORD;
char* pTmp = 0;

*pBufLen = (DWORD)1024;

for(int i=0; i<1024; i++)
pUrl[i] = 0;

pHeaderInfo->GetHeader(pCtxt->m_pFC, "url", pUrl, pBufLen);

if(strstr(pUrl, ".wma")){
if(pTmp=strstr(pUrl, "?"))
*pTmp = '\0';

pHeaderInfo->SetHeader(pCtxt->m_pFC, "url", pUrl);
}


delete pBufLen;

return SF_STATUS_REQ_NEXT_NOTIFICATION;
}
