download loop msHTTPExecuteRequests() ?

[robert fritz]

Dear List,

I have a small application on top of php-mapscript. One project uses WMS layers. There are displayed in the map-window, but if I try to print the map, I get a strange error - message:
scalefactor = 0.52007 scalefactor = 0.52007 HTTP: Starting to prepare HTTP requests. HTTP request: id=1, http://www.geoserver.nrw.de:80/GeoOgcWms1.3/servlet/GEPNRW?LAYERS=GEPNRW%3AGEP%2520Gesamt&REQUEST=GetMap&SERVICE=WMS&FORMAT=image%2Fpng&STYLES=&HEIGHT=2584&VERSION=1.1.0&SRS=EPSG:31492&WIDTH=1824&BBOX=2571639%2C5682644%2E791666667%2C2572708%2C5684159%2E208333333&TRANSPARENT=TRUE&EXCEPTIONS=application/vnd.ogc.se_inimage HTTP: Before download loop msHTTPWriteFct(id=1, 308 bytes) HTTP: After download loop msHTTPExecuteRequests() timing summary per layer (connect_time + time_to_first_packet + download_time = total_time in seconds) Layer 1: 0.030 + 0.019 + 0.030 = 0.079s msDrawRasterLayerLow(WMSGEP): entering. 

For printing, a new map is created to increase the quality and to create a pdf.
The error-message appears, when the request for printing is made. I use the same php script to create a map for display in the browser and for printing - only the image-size and the scale differs. What does the error means?

regards,
Robert
