Hello Ping (and Galaxy-devs) Did this get resolved? We are still on 18.09 and serving our production instance with a proxy prefix, and one of my users has hit this issue when trying to access the "Workflows" tab from the main page. As Ping says, it appears that Galaxy is inserting an extra copy of the prefix into the target URL - if the user removes this manually then the page loads okay. Does anyone know, is there a fix for this in 18.09? Thanks!

It has problems of resolving some of the links, including: workflow visualize -> create visualization shared data -> workflows shared data -> visualizations I will use workflow as an example to illustrate what happens. When the mouse cursor is put on workflow, the URL shown in at the left bottom of the browser shows https://xxx.xxx.tamu.edu/galaxy/workflows/list But after I clicked 'workflow', the real URL shown in the address bar is actually https://xxx.xxxx.tamu.edu/galaxy/galaxy//workflows/list?__identifer=sk0xsywi... Of course, there is no such a page and the browser shows a blank page. If I manually remove one galaxy in the URL, the page is correctly shown. Beside the four mentioned above, other links work fine. If galaxy is configured without prefix, then there is no problem. I also tested v18.05. With all the configuration being the same, this version doesn't have the problem with prefix like v18.09 does. So I think this is a bug in v18.09 with URL prefix. Ping
