Create test page for $other filter option

[Ross]

Background

A test page does not exist for testing if the $other filter option works.

According to ​MDN, resources marked Other are "Resources that aren't covered by any other available type." Looking through the Chrome ​source, Chrome marks resources as Other if their mimetype includes octet.

What to change

• Create a new test page.
• Add it to the list of test pages.

To investigate:

• Have the test page make a request for some random binary data with the mimetype octet.

Note that these are the resource types recognized by the browser. They don't map 1-to-1 to the request types used in Adblock Plus. All types Adblock Plus doesn't have a respective filter option for (i.e. csp_report, speculative, web_manifest, xbl, xml_dtd and xslt) also match $other.

Note that for most requests the resource type is determined by the context in which the resource is loaded (e.g. when loading an <img> element the type is always image) regardless which mime type was sent by the server.

Ah, okay that makes sense.

I'm aware of that.

I played around with this and my results were:

csp report:
Not allowed to use report-uri\report-to in a CSP <meta> tag. Haven't tried doing something with a header instead.

speculative:
I couldn't figure out how to trigger this type of request. I had a go with various preload entries but I think that's not what I should be looking at.

web_manifest:
I tried this and didn't get it to work, but feel I need to try again.

xbl\xml_dtd\xslt:
I tried various methods of including XML documents with DTD or XSLT. If it's inline, there doesn't seem to be a request for things like the DTD. If it's in a frame, it appears as a subdocument as you say. I also tried messing around with different SVG definitions.

Arthur, do you have any example of the $other filter option matching anything in the wild?
