repeatedly requesting /rules.abe

[AlbertMTom]

Using a tool such as the Live HTTP Headers extension (https://addons.mozilla.org/en-US/firefo ... p-headers/), and visiting such as the Wikipedia entry for NoScript (https://en.wikipedia.org/wiki/NoScript), you will see that NoScript will repeatedly request /rules.abe from bits.wikimedia.org ... this presumably has to do with the refresh header which is returned along with the 404 status code.

[barbaz]

To disable that:
NoScript Options > Advanced > Abe > un-check "Allow sites to push their own rulesets"

[AlbertMTom]

I am reporting a bug. NoScript sends multiple requests for the same non-existent file during the course of a single page load.

I am reporting a bug. NoScript sends multiple requests for the same non-existent file during the course of a single page load.

Thank you, looking into it.

With "Allow sites to push their own rulesets" checked, when there's a 400 Bad Request response, the same request gets sent again for each object on that domain ...

[barbaz]

already reported? viewtopic.php?f=10&t=20136

[RobertDrew]

Yeah, I guess it's the same issue, that NS doesn't cache responses with codes such as 400 or 404.

Thanks, merged.
