CSRF, CORS, and HTTP Security headers Demystified
This on Hacker News today: CSRF, CORS, and HTTP Security headers Demystified.
The above article referred to OWASP SameSite doco, and you can read about how to implement that with PHP.
“REST” interfaces
I just wanted to get something that I’ve thought for many years on record, because I don’t think I’ve ever had the chance to discuss it much before, but I believe JSON web services (“REST APIs”) and web applications should deal only in two HTTP verbs, being: GET and POST. You use GET for queries and you use POST for submissions. All POST operations go through business logic for particular services and CRUDing URLs is a supremely bad idea, in my opinion. Just wanted to get that on record. Thanks. p.s for web applications you should 3xx on success, not 2xx on success; what you do for JSON web services is up to you, but for those 2xx is probably fine.
Falsehoods Programmers Believe about REST APIs
A fun read: Falsehoods Programmers Believe about REST APIs.

Today I learned about the Retry-After HTTP header. It was mentioned over here.

This popped up on r/programming today: HTTP(S) Benchmark Tools.

To disable the HTTP Referrer (Referer) header in Firefox open about:config and set network.http.sendRefererHeader to zero.
A folder named ~/.cache/kioexec/krun/13821_0/ already exists
2017-12-09 jj5 – TODO: document this on my blog…
On Debian GNU/Linux 9.1 (stretch) when I try to open an *.desktop (application/x-desktop) link in a browser I get:
A folder named ~/.cache/kioexec/krun/13821_0/ already exists.
Searching for:
A folder named kioexec krun already exists
turned up diddly squat.
I solved the issue (for me) by changing:
System Settings -> Personalization -> Applications -> Default Application s-> Web Browser
from:
Open http and https URLs in an application based on the contents of the URL
to:
Open http and https URLs in the following browser: firefox
If Apache2 won’t serve your JavaScript file try…
I had an issue with Apache2 improperly serving a JavaScript file which I seem to have fixed by making sure the file was terminated with a new-line character… this was really hard to diagnose and resolve! The behaviour in Firefox was that the file just didn’t finish to download, whereas the Apache2 logs indicated a 200 result… I think it may have had something to do with automatic compression, which is a dark art that I do not understand (mumbles something about mod deflate…).
