QUESTION
I have succeed to run Scrapy with Tor using this link: http://pkmishra.github.io/blog/2013/03/18/how-to-run-scrapy-with-TOR-and-multiple-browser-agents-part-1-mac/
But i couldn't run Splash with Tor.
In Scrapy-settings.py I directed to polipo for http_proxy(8123 is polipo port):
...ANSWER
Answered 2017-Jul-20 at 21:18You need to
- make Tor accessible from Splash Docker container;
- tell Splash to use this Tor proxy.
For (2) you can use either Splash proxy profiles or set proxy directly, either in proxy argument, or using request:set_proxy in splash:on_request callback a Lua script. For example, if Tor can be accessed from Splash Docker container as tor:8123, you can do a request like this:
QUESTION
How do HTTP caches store their requests ? Is there a commonly used protocol for caching requests or does each implementation have its own method for caching ?
EDIT : By this I mean how do the servers PHYSICALLY store cached requests, once the decision to cache has already been made.
I was looking through the functionality of some HTTP cache implementations such as polipo and found that they store (at least) part of their cache in the local file system but later found that nginx caches files/ file content (meaning there's a more efficient method for accessing cashed requests than storing them in the file system).
I was playing around with possible ideas and I tried to implement this method:

Answered 2019-Jun-26 at 18:07Is this because of the
(hashval % size)
line ?
No, of course the modulo division increases the possibility of collisions but even without using it you can get duplicate cases, a perfect hash is quite difficult to achieve, not to say impossible when the samples are random. I suggest you to find a hashmap implementation managing collisions (where every node in the hash table stores a link to the next collisioned key which you have to compare with your string)
QUESTION
I do webscrapring with Scrapy, using Polipo as proxy, and Tor as network. I know my proxy makes rotating IP, but the IP location is most of the time out of my country. On the websites I scrape, it could have some blocking considering the location of the IP. Then, how can I keep the rotating IP rule and to limit the location of the IP used?
Scrapy version: 1.5.0, Python version: 2.7.9, Tor version: 0.3.4.8, Vidalia: 0.2.21
...ANSWER
Answered 2018-Nov-14 at 19:48Most probably you know this but the final ip which the website you are scraping it will see the ip of the exit node. As such you can control the country of the exit node using configuration
You can run multiple tor set up and mix and match or rotate tor service across your request set.

I have installed tor
via apt
