WebServer.serveStatic: index.html.gz as default doesn't work (while index.html does)

[JasperHorn]

Apologies for forgoing the prescribed format. I noticed this problem while reading the code and though I did test it, that does make things like hardware information irrelevant. I decided to cut out that noise instead. (The issue that this is related to also didn't follow that format...)

Using index.html instead of index.htm for the "folder" is supported since 9f2cfb8

At that time, the lookup order became:

1. index.htm
2. index.html
3. index.html.gz

As #6792 pointed out, this broke support for index.htm.gz and this was changed in 6768116 . The lookup order now is:

1. index.htm
2. index.html
3. index.htm.gz

However, this has removed support for using index.html.gz completely. I think the lookup order should include four items:

1. index.htm
2. index.html
3. index.htm.gz
4. index.html.gz

(Perhaps with 2 & 3 reversed.)

2 and 3 should be reversed.
Can you please make a PR with your suggestion?

[earlephilhower]

2 and 3 should be reversed

I would humbly suggest that anyone evil enough to have both a index.htm.gz and a index.html and expect for a sane solution gets the randomness they deserve.

Thanks for picking this up during my radio silence. I was still planning to get back to this, but had since moved on to non-esp projects and didn't get around to this.

Now there's just my other (accepted) pull request which is in need of a follow-up...
