@LouisPortier said in Redirection chain and Javascript Redirect:

Hi,

A redirection chain is usually defined as a page redirecting to another page which itself is another redirection.

URL1 ---(301/302)---> URL2 ---(301/302)---> URL3

But what about Javascript redirect? They seem to be a different beast:

URL1 ---(301/302)---> URL2 ---(200 then Javascript redirect)---> URL3

From what I know if the javascript redirect is instant Google counts it as a 301 permanent redirection, but I'm still not sure about if this counts as a redirection chain.

Most of the tools (such as moz) only see the first redirection.

So is that scenario a redirection chain or no?

A JavaScript redirect, on the other hand, is a redirect that occurs using JavaScript code embedded in a webpage. Instead of relying on server-side redirects, JavaScript redirects are triggered when the page loads or when certain conditions are met, and they instruct the browser to navigate to a different URL. They can be used for various purposes, such as redirecting users after a certain amount of time, after a form submission, or based on user interactions.

I appreciate your detailed explanation. To enhance accuracy in tracing redirects, ensure a cohesive sequence. Consider using a unified approach for hash numbers, perhaps generating a unique identifier for each transition. Additionally, refine the code logic to account for different redirection techniques, ensuring a seamless and connected mapping of the entire journey from A to D. If possible, share snippets of your code for more targeted guidance. shopify website design servicee austin

Thank you for the valuable feedback. While the current code successfully executes, it lacks accuracy in tracing the redirect sequence. The issue stems from the disjointed nature of the captured redirects, as seen in the isolated transitions from A to B, B to C, and C to D, where randomly generated hash numbers (channel_1 and channel_2) are utilized. This disrupts the continuity of the redirect chain, resulting in an inaccurate representation of the actual progression from A through D.

The objective is to effectively track the entire journey, encompassing transitions from A to B to C to D, across various redirection techniques such as meta-refresh, JavaScript, and HTTP redirects. I would greatly appreciate your guidance on refining the code to maintain the integrity of the redirect sequence, ensuring a connected and sequential mapping of the redirection process. Liteblue

In the scenario you described, where there is a sequence of redirects involving both HTTP redirects (301/302) and a JavaScript redirect, it can be considered a redirection chain. The key point is that each step in the sequence contributes to the final destination of the URL.

In your example:

1. URL1 redirects to URL2 using an HTTP 301/302 status code.
2. URL2, after an HTTP 200 response, triggers a JavaScript redirect to URL3.

From Google's perspective, if the JavaScript redirect is instantaneous and does not introduce a delay, it might treat it similarly to a traditional 301 permanent redirect. However, it's important to note that search engines may interpret JavaScript redirects differently, and their behavior may evolve over time.

Tools like Moz may sometimes focus on the initial HTTP redirect and not delve into subsequent steps, potentially overlooking the complete redirection chain. Therefore, discrepancies in what different tools report could occur.

For a more comprehensive understanding, you might consider using tools or methods that specifically analyze JavaScript-based redirects or inspect the network requests in a browser's developer tools to see the entire redirection sequence. This way, you can get a clearer picture of how search engines and various tools interpret the entire redirection chain, including both HTTP and JavaScript redirects.

Thank you for the insightful feedback. While the current code executes successfully, it falls short in accurately tracing the redirect sequence. The issue lies in the disjoint nature of the captured redirects, exemplified by the isolated transitions A->B, B->C, and C->D, where the hash numbers (channel_1 and channel_2) are generated randomly. This disrupts the continuity of the redirect chain, failing to reflect the actual progression from A through D. The goal is to effectively track the entire journey, A->B->C->D, across different redirection techniques such as meta-refresh, JavaScript, and HTTP redirects. Could you provide guidance on how to refine the code to maintain the integrity of the redirect sequence, ensuring a connected and sequential mapping of the redirection process?

Thank you for your feedback. While the code is currently functional, it doesn't yield the expected outcome. The recorded redirect chain appears disjointed, capturing transitions like A->B (channel_1 -> channel_2), B->C (channel_1 -> channel_2), and C->D (channel_1 -> channel_2). The issue lies in the randomly generated hash numbers (channel_1 and channel_2), preventing the proper linkage of the redirect chain. The goal is to accurately capture sequential events such as A->B->C->D, considering various redirection methods like meta-refresh, JavaScript, and HTTP. How can I modify the code to implement this strategy and ensure the redirection chain is connected as intended?

Thank you for your feedback. Although the code is functional, it does not produce the expected result. Currently, the recorded redirect chain is disjointed, capturing transitions like A->B (channel_1 -> channel_2), B->C (channel_1 -> channel_2), and C->D (channel_1 -> channel_2). In this case, the hash numbers (channel_1 and channel_2) are randomly generated, preventing the proper linking of the redirect chain.

thx, the code works, but not as expected: A->B->C->D (channel_1 -> channel_2 -> channel_3 -> channel_4).

In my case it will record a redirect chain of A->B->C->D like:

A->B (channel_1 -> channel_2), than B->C (channel_1 -> channel_2), C->D (channel_1 -> channel_2); where channel_1 & channel_2 are random hash numbers.

So I can not link the chain together. that would be the strategy to capture the chain of events (while the pages redirect using, meta-refresh, javascript, http...)? Liteblue USPS

window.location.replace('http://example.com');

It's better than using window.location.href = 'http://example.com';

Using replace() is better because it does not keep the originating page in the session history, meaning the user won't get stuck in a never-ending back-button fiasco.

If you want to simulate someone clicking on a link, use window.location.href

If you want to simulate an HTTP redirect, use window.location.replace

You can use assign() and replace methods also to javascript redirect to other pages like the following:

location.assign("http://example.com");

The difference between replace() method and assign() method(), is that replace() removes the URL of the current document from the document history, means it is not possible to use the "back" button to navigate back to the original document. So Use the assign() method if you want to load a new document, andwant to give the option to navigate back to the original document.
