QUESTION
I am trying to ping websites from Firebase Cloud Functions.
When deployed, it fails with small websites: it returns 10s timeouts, HTTP code 403, HTTP code 508...
NB:
-The Cloud Function is executed successfully
-No error message gets printed
-It works fine when running locally (with emulators)
-It works fine when targeting big websites (such as google.com)
What is going on?
Could it be anti-DDOS software blocking the requests from Firebase IPs?
Does the IP of the server running Functions stay the same over multiple calls?
Any help welcome, I am in the dark here...
Edit: Here is a minimal sample: the function:
...ANSWER
Answered 2020-Nov-03 at 16:18I confirm that some sites detect that my requests come from a datacenter and do not reply nicely. It does not happen when running locally because in this case my request is emitted from my home IP. Going through a proxy solves the issue.
QUESTION
I’m currently using selenium in a web bot to purchase items on a website. When I search for the item I want to buy and it cannot be found I use driver.navigate().refresh()
to refresh the page to see if it is there now, it will keep doing this until it finds the product when it is released on the page. However, I wish to start my bot a few hours before the release of the product which currently doesn’t work as after roughly 30 seconds of refreshing the page I get banned from the page due to the anti-ddos software they use. One option is to increase the delay between refreshing, however I need to catch the release of this product as soon as possible so I’m trying to find a way that my program can wait/sleep until 30 seconds before the release however I’m struggling to find a way to do this.

I have an application that is meant to interact with a remote API. I have to make around 10000 (10k) requests without having it be too fast that anti-ddos protection will block me. Means I need to add a small delay.

...ANSWER
Answered 2018-May-20 at 23:42The answer depends on how fast you want to try and make it. How many requests you are allowed to do simultaneously, etc. Here is a possible strategy. The way you want to think about this, is figure out how many concurrent requests you are allowed to make, and break the work up into synchronous blocks that all run concurrently.

I'm working on minimizing my site and I'm seeing that bag2
appears 5 times in my files waterfall. My site takes 1.6 seconds to load but one bag2
file takes 800 seconds to load, although it's size is only 7.0 kb.
What are these bag2 files and how can I remove them to make my website faster? I like Cloudflare's anti-DDOS protection, but I'm annoyed with the rest of it.
...ANSWER
Answered 2017-Apr-17 at 18:55These are a part of CloudFlare's "Rocket Loader" feature. If you disable that feature, it should disable serving the bag files from cdn-cgi.
