Fix Flex Gateway Regex

@Sohailzk

Hi, I can fix this quickly. I will create a working regex that allows all countries after /name/ except japan, and ensure routes like /name/china and /name/america work properly. I have experience with Flex Gateway, API routing, regex, and REST APIs, so I can start immediately and complete this fast. Thanks, Sohail

Your negative lookahead `/name/(?!japan)` is missing the rest of the path pattern - that's why it's not matching anything. You need `/name/(?!japan)([^/]+)` to capture the actual country name after excluding japan. I've debugged similar regex routing issues in my API projects, including a trading platform integration that needed specific endpoint filtering. The fix involves properly capturing the country parameter while maintaining the negative lookahead. You can see my API work at ffulb.com. Ready to get this working today - just need to test the corrected pattern against your Flex Gateway setup.

Hi, To ensure your Flex Gateway route properly accepts any country name after `/name/` but specifically filters out "japan," I will craft a precise regular expression. Instead of using the negative lookahead that your earlier attempt employed, I will create a simpler expression that captures any word following `/name/` while excluding "japan" through alternative logic. I can implement a robust solution using a combination of regular expression techniques along with testing to ensure it behaves correctly in your API environment. Through careful validation, we can confirm that paths like `/name/china` or `/name/america` work seamlessly while the unwanted `/name/japan` is consistently blocked. As for my background, I'm Muhammad Furqan, and I specialize in API development and integration, which includes optimizing routing rules like yours. Could you confirm if there are any additional countries you want to exclude in the future? Also, is there a specific testing framework you prefer for API validation? Looking forward to discussing your requirements further! Thank you, Muhammad Furqan

Hi there, I see your Flex Gateway route fails because the negative lookahead /name/(?!japan) isn’t accepted, causing the match to break and return 404. I’ve spent the last 5 years fixing API routing issues exactly like this, especially with strict gateway regex engines. I can provide a compliant pattern that correctly matches any /name/<country> except "japan". I’ll verify it against Flex Gateway’s regex parser, test valid cases like /name/china and /name/america, and ensure /name/japan is the only blocked path. Once applied, your route will match reliably and avoid false 404s. Thanks, Arvin Jay

Hello, I’ve gone through your requirement and understand that you need a working solution to allow dynamic country paths while specifically blocking “japan” in your Flex Gateway route. With experience in API development and gateway configurations, I’ve handled similar routing and filtering challenges. What I can help you with: • Implementing a working route pattern for dynamic country names • Applying a reliable method to block “japan” without breaking routing • Providing clean, maintainable configuration (regex or policy-based) • Ensuring correct routing behavior with zero 404 issues Warm regards, Monica Bhatia

Hi, I can provide a regular expression that meets your needs for the Flex Gateway route. The goal is to allow paths like /name/china or /name/america while ensuring that /name/japan is blocked. Given my experience with regex and API routing, I understand how to craft expressions that are both effective and compatible with gateway configurations. A potential solution could be using a regex like `/name/(?!japan$).*`, which allows any country name except Japan. Once implemented, this should route correctly and ensure /name/japan returns a 404. If you have any specific conditions or edge cases you'd like to discuss, feel free to let me know. Looking forward to your response so we can implement this solution efficiently. Thank you.

I’ve reviewed your Flex Gateway routing issue and I can fix the regex quickly. Flex Gateway uses the RE2 engine, which has specific limitations (no lookahead/lookbehind), and that’s why your current pattern is not working as expected. Here is what I will deliver: • A corrected regex fully compatible with Flex Gateway (RE2) • A short explanation of the fix • A clean example of how to apply it in your route configuration • Optional: a minimal YAML snippet to help you validate the rule This is a straightforward task for me and I can provide the working solution immediately. Payment is only required at the end of the work, once you have tested and confirmed everything is working correctly. No upfront payment. Best regards,
