Some thoughts on your pull request:
- since you are submitting a docs enhancement, be sure to consider all
platforms (e.g. in your example also include options for Windows users,
where there is no 'tail' command)
- consider submitting your request to the branch-7-0

thx Fabian,
indeed you are right. However, is this then a bug or a feature?
In any case, I thought it might be helpful to improve the documentation to
a) point out that use of OGC compliant requests is possible and b) that for
creating png it is important to remove first 3 lines.
See pull request https://github.com/mapserver/docs/pull/121 .

Renzo,
As far as I remember you have to remove the HTTP headers from the
response (the first 2-4 lines or so) when you use mapserv -nh with OGC
services.

Fabian

Hi All,
I have installed mapserver 6.4.1 in a docker container based on
debian jessie (see dockerfile below)
If I run:
/usr/lib/cgi-bin/mapserv -nh
"QUERY_STRING=EXCEPTIONS=application/vnd.ogc.se_inimage&REQUEST=GetMap&SERVICE=WMS&VERSION=1.1.1&map=/genes-mapserver/wms_test.map&SRS=EPSG:4326&BBOX=-180,-90,180,90&FORMAT=image/png&WIDTH=1080&HEIGHT=614&STYLES=&LAYERS=satellite_mod"
/tmp/test.png
The png is corrupt and I can not open it with neither gimp nor
firefox.
However, I get valid pngs using the very same map file with
shp2img or mapserv -nh
"QUERY_STRING=map=/genes-mapserver/wms_test.map&mode=map&layers=satellite_mod
.
Find below more details (mapserver version, exact command lines
I used and resulting debug logs, map file, and docker file)
I searched google, the mailing list archives, but nothing seems
to be similar to this problem. Therefore, any help is very much
appreciated :)
ciao, renzo
