HTTP 499 Status Code: Proxy IP Resolves Client Closing Connection Issue

What the heck is HTTP 499? Let's figure out what the problem is.

Anyone who's ever developed a web site has seen this piece of crap code - HTTP 499.The client suddenly quit.For example, the user can't wait for the page to load and closes the browser. At this time, the server has not yet finished passing the data, only to write down this abnormal state. Especially like our usual case of swiping the video stuck directly scratched away, leaving a 499 mess on the server side.

What makes proxy IPs a cure for this?

Using a proxy IP is like adding a proxy IP to a network connectionbuffer spring, focusing here on three real-world scenarios:

1. Automatic switching when the network is jerking: Normal direct connection is like walking on a log bridge, once it breaks, it's over. ipipgo's proxy pools areMore than 200 city nodesLine A is jammed. Cut to line B in a second.

2. Intelligent retry request timeout: set 3 seconds timeout automatically change IP resend, than the user patience to try a few more times!

3. Load balancing does not pile up: the request is dispersed to different proxy IP, to avoid a single server is bursting

 Python example: automatic retries with ipipgo
import requests
from ipipgo import get_proxy

def safe_request(url):: for _ in range(3): for
    for _ in range(3).
        try: proxy = get_proxy()
            proxy = get_proxy() Automatically get the latest IPs
            return requests.get(url, proxies={'http': proxy}, timeout=5)
        except: proxy = get_proxy()
            continue
    return None

Hands on with ipipgo for the 499

Follow these three steps, and even a white person can get started right away:

Frequently Asked Questions QA

Q: Is it illegal to use a proxy IP?
A: As long as you don't do anything bad and completely legal, ipipgo all IPs have been formally filed, rest assured that with the

Q: What is the difference between a free proxy and ipipgo?
A: It's like the difference between a public restroom and your own bathroom, which free agents encounter all the time:
- The IP just expired.
- It's slower than a bicycle.
- Surreptitious recording of data

Q: Will the 499 still come out after the configuration of the agent?
A: I don't dare say 100% eradication, but it can be reduced80% and aboveThe probability of. If it still occurs frequently, it is recommended to check:
1. Is the local network not jerking around?
2. whether the target website has an anti-climbing mechanism
3. Isn't it time to upgrade the proxy package?

Personal advice on stepping on potholes

Two final rants about real-world experience:
1. Don't be stingy.: Free agents look to save, but the actual waste of time is more expensive!
2. take turnsSet the frequency of IP switching, don't catch one and gripe hard!
3. Look at the logs.: Analyze the time pattern of 499 appearing every week to treat the symptoms

Honestly, since using ipipgo'sCommercial level agents, the 499 error reporting on my end has dropped from dozens of times a day to single digits. Theirs.Intelligent RoutingIt does have two brushes that automatically pick the node with the lowest latency. There's also a failure compensation mechanism that came out recently, which makes it even more hassle-free to use.
