Url_rewrite with full url doubles path


my relative url rewrite works fine

match: /my/articles
rewrite_to: /v1/articles

but as soon as i use a full url:

rewrite_to: http://api.mydomain.com:3000/v1/articles

it stops working and Log browser shows path “/v1/articles/v1/articles”

Any idea for a fix or a workaround?
Thank you.

Hi Juraj,

can you share your API definition ?

Sure, the whole definition is huge, but this part should be sufficient, let me know if anything’s missing:

                        "rewrite_to": "http://api.mydomain.com:3000/v1/artists"

you don’t need to include your host in rewrite_to.
So if you remove that (so you’ll have "rewrite_to": "/v1/artists") then /me/artists should be rewritten to /v1/artists.
If you are still having issues, you may also check this ticket which has been resolved.

Let me know if you need any further help.

Sorry Kos, but i do have to use the full url, because the default Target URL
has a different port (3001). And for some URLs, i need to go to port 3000.
I think it’s a bug, that Tyk gateway rewrites this path to


Does it work if the target and the rewrite domains are completely different (apart from the port?)


Hi Martin,

it doesn’t work either. I tried both a different domain/port, and a differnt domain without a port number.
Both responses clearly show a request path “/v1/artists/v1/artists”


Ok thanks for confirming - we’re going to try and replicate to see if there’s a regression somewhere.

We’ve been able to reproduce this and we’re tracking the issue over at GitHub: URL rewrite duplicates endpoint path · Issue #855 · TykTechnologies/tyk · GitHub
