The documentation says that you can add a "query_string" parameter in a HTTP measurement but the anchor seems to ignore it?
The anchors' HTTP service is described here: https://atlas.ripe.net/docs/howtos/anchors.html#ripe-atlas-anchor-services - basically agreeing with you, it ignores query parameters.
A colleague suggests that it can be useful to disable caching if the poor probe is locked behing a transparent HTTP proxy with caching.
{'is_oneoff': True, 'definitions': [{'description': 'HTTP GET to fr-par-as2486.anchors.atlas.ripe.net', 'af': 6, 'type': 'http', 'target': 'fr-par-as2486.anchors.atlas.ripe.net', 'method': 'GET', 'path': '/', 'query_string': 'disablecaching=123456789', 'https': False, 'more_extended_timing': True}], 'probes': [{'requested': 1, 'type': 'area', 'value': 'WW', 'tags': {'include': ['system-ipv6-works']}}]}
It is hard to judge a particular HTTP proxy's behaviour, but indeed adding some variance to the URL via the query string likely helps here. Regards, Robert
