Show Intermediate Rapid resolver page before redirecting to Ensembl site #14

shashankbrgowda · 2025-08-21T06:45:05Z

This PR adds a redirect webpage before redirecting to Ensembl beta site from Rapid site. It automatically redirects to Ensembl site from Intermediate page after 10 seconds.

Fixes ENSWBSITES-2952

Example redirect views (For local testing use http://localhost:8001/rapid/)

Home page
https://resolver.ensembl.org/rapid/
Blast page
https://resolver.ensembl.org/rapid/Blast

target="_blank" will open the beta site in a different tab. Shouldn't it open in the same tab?

I've removed it. There is no need to click on it as Its redirected automatically in the same tab. Not sure whether we need to open the url in new tab when user clicks on it

Is the Lato font loaded anywhere?

-            return resolved_response(url, request)
+            response = ResolvedURLResponse(
+                response_type=RapidRedirectResponseType.INFO,
+                status_code=308,


I am confused about the relationship between the content of the page and the http status code.

If the server responds to the requested url with an html page, then shouldn't the http status code be 200? If the server redirects to a url that is different from the requested url, then the http status code should be in the 300 range. Perhaps I am misunderstanding the code here, but is the server responding with an html page, on the same url as was requested, but combines this response with a 308 http status code?

I renamed the field to code.

Rapid resolver has 2 responses

Json (when we pass application/json header)

Html

There is no direct URL redirect now, You either get Json or Html response. Redirect happens after 10 seconds of opening the rapid redirect page.

If application/json header is not passed, Html page always renders irrespective of the error and the error message will be displayed on the webpage with the status code in the venn diagram. The status code to be displayed in venn diagram is stored in ResolvedURLResponse.

We don't return 3XX code for Json.

For Html 3XX status code will displayed in the web page but API return code will be 200.

Here is sample json request/response

curl -X 'GET' \ 'https://resolver.ensembl.org/rapid/Camarhynchus_parvulus_GCA_902806625.1' \ -H 'accept: application/json'

{"resolved_url":"https://beta.ensembl.org/species/2df86696-b80f-475c-b327-590a36260c6e"}

The reason I don't return 3XX for Json response is because Swagger doesn't handle 3XX response codes. We don't actually need Json response but its needed for Swagger.

+            {{ url_helper.render_url("https://beta.ensembl.org/") }}


To which page on the beta site will the user be redirected?

I'm not sure to which page we need to redirect in case of error

For 404, the XD suggests to redirect to Species selector. For other errors, where (by definition) there is no succesfully resolved URL, we can use 404 template (with redirect to home page or species selector), or skip redirection altogether (only showing the error message).

please check if you need all those font weights and font styles. Also, why roboto? And why is Lato italic both times?

I don't have dev version of XD. I'll update it after checking the XD

For now removed italics and Roboto and kept light, regular, bold weights.

+                resolved_url=url,


The ticket also mentions the case of multiple resolved URLs (code 300), which is not addressed here. In principle an assembly accession ID can resolve to multiple genome UUIDs (if it's part of both partial and integrated release, like the human reference), but it shouldn't apply to rapid species so it's fine (assuming any rapid assembly won't become part of a partial release in the future).

Looks good. Not sure if we need to change anything for error redirection, but it should work well as-is.

azangru · 2025-08-28T13:58:03Z

This may be somewhat tangential to the scope of your PR; but I don't think /rapid/Blast is a correct url pattern.

If you visit the rapid site, you will find there two url patterns for the BLAST page:

https://rapid.ensembl.org/Multi/Tools/Blast
https://rapid.ensembl.org/<assembly_name>/Tools/Blast (e.g. https://rapid.ensembl.org/Camarhynchus_parvulus_GCA_902806625.1/Tools/Blast)
In both cases the redirect should be to https://beta.ensembl.org/blast. My point is, however, that, according to the traffic manager rules, it will never send traffic to simply https://resolver.ensembl.org/rapid/Blast

azangru · 2025-08-28T14:20:24Z

The following url breaks:
https://rapid.ensembl.org/Agrilus_biguttatus_GCA_963921985.1/Location/Genome

How should the interstitial page work for the id page?

While it isn't within the /rapid namespace, it works for gene stable ids of rapid species:

It probably makes sense to create a rapid/id/:id path that would reuse the same handler. Probably with a certain modification: for the /rapid/ namespace, this handler should always show an intermediary html page, whereas without that namespace, it should only show an intermediary page if there are more than 1 match (otherwise it should just redirect to the relevant page)

This can be addressed in another PR along with id page
