Short URL Encoding for Browser Buffer Overflow Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face login failures and redirection issues due to URL length limitations when users need to access pages that require login, as the combined URL exceeds browser buffer limits, leading to incomplete information and failed login or redirection.
Innovation Solution
Generating a short URL by encoding a portion of the original page address, such as using MD5 hashing, to redirect the client to a login server, thereby reducing the URL length and preventing buffer overflow, and using external or internal redirects to manage website access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the original URL is appended to the login server URL to enable redirection, then the login process can be completed, but the URL length exceeds browser buffer limits causing login failure
Solution Approach 1:
The patent segments the original URL into multiple parts (domain name, path, query parameters) and selectively encodes only the necessary portions. This segmentation allows the system to maintain URL functionality while reducing overall length to fit browser buffer limits.
Solution Approach 2:
The patent introduces an intermediary encoding mechanism (such as base64 encoding or custom shortening algorithms) that acts as a mediator between the original URL and the login server URL. This intermediary transforms the long URL into a shorter representation that can be safely appended without exceeding browser limits.
2Length of stationary object
If URL encoding is applied to reduce length, then browser buffer limits are satisfied, but URL integrity and readability may be compromised
Solution Approach 1:
The patent implements a feedback mechanism where the encoding process is designed to be reversible. The system encodes the URL in a way that preserves all necessary information, and the decoding process at the login server restores the original URL exactly, ensuring no information loss despite the transformation.
Solution Approach 2:
The patent changes the parameter representation of the URL by applying encoding transformations (such as base64, hex encoding, or custom compression). These parameter changes reduce the visual length of the URL while maintaining all original information in an encoded format that can be fully recovered.

AI summary
Managing website access for a user who is initially not logged in to the website includes: receiving a request sent by the user via a client to access a webpage that requires the user to log into the website, the request comprising an original page address of the webpage (502); encoding at least a portion of the original page address to generate an encoded portion; generating a short address that includes the encoded portion; redirecting the client using the short address (504); maintaining a mapping of at least the encoded portion and the original page address; redirecting the client to a login server for the user to perform login using a login address that is based at least in part on the short address (508); redirecting the client based at least in part on the short address (512); and determining the original page address.
