[mapserver-dev] mapserv 6.4.3 -nh is not working

[Lime, Steve D (MNIT)]

Works for me with regular MapServer URLs, e.g.:

    /usr/local/mapserver-6-4/bin/mapserv -nh QUERY_STRING='mode=map&map=polygon-examples-hatch.map' > junk.png

But with a WMS GetMap url it's not working, at least on my box. Works as expected with 7.0. Was this working before 6.4.3?

Hi Devs,

I have found a problem with 6.4.3 while debugging another issue in that 
-nh is not suppressing the 'Content-Type: image/png' header:


$ /usr/local/bin/mapserv -nh 
QUERY_STRING='MAP=./test.map&FORMAT=image%2Fpng&MAP_IMAGETYPE=agg_qn&LAYERS=Australia&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&SRS=EPSG%3A900913&BBOX=12813560.707781,-2467980.3837369,12814292.234029,-2467467.4196173&WIDTH=1225&HEIGHT=859'

This is based on a clean build and install.

Can someone verify this or point me at the error in my ways. I'm happy 
to open an issue if you want one.
