Jeff, I screwed around on the debug_level variable, and found in cache.log the following lines: 2009/05/04 11:58:39.891| WARNING: HTTP header contains NULL characters {Server: 4D_v11_SQL/11.4.0 Date: Mon, 04 May 2009 09:58:39 GMT Cache-Control: max-age=0, private, must-revalidate Connection: close Content-length: 365 Content-Type: text/xml Expires: ue, 04 May 99 09:58:39 GMT} 2009/05/04 11:58:39.891| HttpMsg::parse: cannot parse isolated headers in 'HTTP/1.0 200 OK ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Server: 4D_v11_SQL/11.4.0 Date: Mon, 04 May 2009 09:58:39 GMT Cache-Control: max-age=0, private, must-revalidate Connection: close Content-length: 365 Content-Type: text/xml Expires: ue, 04 May 99 09:58:39 GMT' 2009/05/04 11:58:39.891| processReplyHeader: Non-HTTP-compliant header: 'HTTP/1.0 200 OK ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Server: 4D_v11_SQL/11.4.0 Date: Mon, 04 May 2009 09:58:39 GMT Cache-Control: max-age=0, private, must-revalidate Connection: close Content-length: 365 Content-Type: text/xml Expires: ue, 04 May 99 09:58:39 GMT' 2009/05/04 11:58:39.891| Unknown HTTP status code: 600 2009/05/04 11:58:39.891| InvokeHandlers: 4694974055C0D959D4D13969B82ED7E9 2009/05/04 11:58:39.891| StoreEntry::InvokeHandlers: checking client #0 2009/05/04 11:58:39.891| ctx: exit level 0 2009/05/04 11:58:39.891| fwdFail: ERR_INVALID_RESP "Bad Gateway" ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Do you believe that this is a server-side problem? A bad HTTP protocol implementation on that particular server? Unfortunatly, I cannot check if that also happens when trying to send tax reports to the officials. I'll take a month until I have the next to send.... Peter > -----Ursprüngliche Nachricht----- > Von: Jeff Pang [mailto:pangj@xxxxxxxx] > Gesendet: Montag, 4.
