[mapserver-users] TR: "ows_http_max_age" have no effect...

[Rousseau Lambert2, Louis-Philippe (EC)]

Oups sorry, pressed the shift key too soon... Here is the complete message/question:


Hi everyone!


I'm trying to set a cache-control maximum age for my web services and am having some difficulties making it work.


I have added the line `"ows_http_max_age" "10800"` in my mapfile (MAP.WEB.METADATA) but the response headers I get (from curl) does not have any cache-control value:


```

HTTP/1.0 200 OK
Date: Thu, 19 Sep 2019 18:08:46 GMT
Server: WSGIServer/0.1 Python/2.7.6
Content-type: image/png
Content-Length: 653383
```

I am using:

MapServer version 7.0.7 OUTPUT=PNG OUTPUT=JPEG OUTPUT=KML SUPPORTS=PROJ SUPPORTS=AGG SUPPORTS=FREETYPE SUPPORTS=CAIRO SUPPORTS=SVG_SYMBOLS SUPPORTS=RSVG SUPPORTS=ICONV SUPPORTS=FRIBIDI SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT SUPPORTS=WFS_SERVER SUPPORTS=WFS_CLIENT SUPPORTS=WCS_SERVER SUPPORTS=SOS_SERVER SUPPORTS=FASTCGI SUPPORTS=THREADS SUPPORTS=GEOS SUPPORTS=POINT_Z_M INPUT=JPEG INPUT=POSTGIS INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE


and here is a minimal working mapfile example, you can use any *TMP_TGL_2* data from
