website: 'Use proxy' when uploading URL seems to hang

[AngieHinrichs]

Hi Theo! When I paste a URL (e.g. https://hgdownload.gi.ucsc.edu/hubs/GCF/000/857/045/GCF_000857045.1/UShER_MPXV_cladeI/mpxv.cladeI.latest.masked.taxonium.jsonl.gz) into the input on taxonium.org, a checkbox labeled "Use proxy" appears, and it's checked by default. If I leave it checked, it seems to hang and never finish loading the tree (even a very small one). If I uncheck it, then it loads as expected. Can that checkbox be removed or unchecked by default? Thanks!

Hi Angie,

Interesting! The proxy exists because for many resources that aren't hosted with CORS enabled, loading hangs without the proxy. For example http://visualisations.pangea-hiv.org/charon/getDataset?prefix=/pol/20210524&ladderizeTree=true&treeType=nextstrain (which is a Nextstrain format tree) but yes - it's very unfortunate if it's stopping your trees loading. My guess is that its probably that it doesn't handle .gz compression and tries to turn stuff into text - I seemed to see some of that in the browser. I'll try to fix that but for now I've made it default to off. :)
