I am using the HTTP Retriever node to fetch multiple product page URL’s. 3 requests return 403 Error responses. These failed requests share the commonality of containing a “?” in the path component of the URL. These question marks do not appear to indicate the start of query parameters - they are possibly a mistake. I’ve never actually seen a URL like this before. Nonetheless, they are successful in the browser. I’ve included a small demonstration workflow with 3 regular URL’s and 3 URL’s containing the mystery question mark. Thanks for your time.

Hi Nacyjay, Many thanks for this. We’ll have a look. Would you be willing to give the pre-release build a try? This already fixes the issue you described [here](https://forum.knime.com/t/using-cookie-retrieved-with-http-retriever-node-doesnt-work-in-workflow-however-copy-pasting-exact-same-cookie-from-web-console-does/27646) and probably this one will be resolved as well. If not, we’ll try to get this fixed for the next release as well. If you would give the pre-release a try, please contact us at mail@palladian.ws Thanks, Philipp ---

I am not sure if there’s anything to fix. All of these URLs (no matter whether there’s a ? or not) give me a 404 when I try to load them in the browser: ![image](https://forum.knime.com/uploads/default/original/3X/0/9/090040c79069dc568cbcd1702215b4160cbb6d4f.png) ---

Hi, that’s strange because all 6 URL’s included in the workflow I uploaded here do work in the browser, and then only 3 work (return 200 status code) in the workflow. ![Screenshot 2020-10-21 at 08.55.05](https://forum.knime.com/uploads/default/original/3X/4/6/46f142feda68a6b2ccb7c41e879cfe62d740680b.png) ![Screenshot 2020-10-21 at 08.55.22](https://forum.knime.com/uploads/default/original/3X/b/d/bd15673f5e227b1f6d01294963daa0fbded15122.png) and yes I will give the prerelease a go, thanks. ---

Hi Nancyjay, received your email – thanks. I will be in touch regarding the prerelease for the next version, this will still take a bit, as we’re currently working on some outstanding issues. Regarding what I wrote below – my apologies. I just realized that I’d need to click on “English” on the website, and only then the links work (that’s why you set the cookie at all, I totally overlooked this 😬 ). So I can confirm that all the links work fine in the browser, but the ones with ? return 404 in the workflow. I think we have addressed this issue in the recent Palladian lib update as well. Thanks for the feedback, and I’ll be in touch about the pre-release (hopefully next week). –Philipp ---
