- As far as I understand the code, the content in the cache is used if it has not expired. This means, that if there is content in the cache (fetched by e.g. check-fetch-times) it should be used if used within expiry time. That would mean, I would have to see the warning on the page if the cache content is valid. This does not happen at all while sometimes I manage to get valid html in the cache by check-fetch-times.
- with 'is not handled correctly' I mean that the warning does not show on the wxadvisory-page if the cache content is valid (see point 1)
- KNMI/temis.nl has been known to block IP addresses : I am not blocked because I get the info after 60-70 seconds. Both from the PHP-scripts and in my browser. I agree it seems a problem at temis. Might have to do with CDN as you have lightning fast results and I have to wait 60-70 seconds.
- I wait for temis first now, then I look again at meteoalarm which may have a similar problem (but I would appreciate it if you could look into point 1 and 2)
To be continued (when I have comment back from temis)
