How to best serve sub folders and files?

[kabukky]

Hi,
I'd like to serve everything that is present in folder called pages. Here's a sample structure:

|____pages
| |____webgl
| | |____Compressed
| | | |____webgl-export.jsgz
| | |____index.html
| | |____Release
| | | |____fileloader.js
| | |____TemplateData
| | | |____default-cover.jpg
| | | |____favicon.ico

Here's what I'm doing with httptreemux:

func pagesHandler(w http.ResponseWriter, r *http.Request, params map[string]string) {
    http.ServeFile(w, r, filepath.Join("pages", params["filepath"]))
    return
}

func InitializePages(router *httptreemux.TreeMux) {
    // For serving standalone projects or pages saved in in content/pages
    router.GET("/pages/*filepath", pagesHandler)
}

This works fine when I open e. g. http://server.url/pages/webgl/Release/fileloader.js.

However, http.ServeFile is supposed to serve the index.html when opening http://server.url/pages/webgl/.
It does that, but the path will be rewritten to the one without a trailing slash (http://server.url/pages/webgl).
This breaks links to files and sub folders in the index.html, e.g.:

<script src="Release/fileloader.js"></script>

which will now link to http://server.url/pages/Release/fileloader.js instead of http://server.url/pages/webgl/Release/fileloader.js.

Thanks
Kai

Ah, that's interesting. As you've surmised, I don't think there's currently a good way to do this.

What I have in mind is an router-level option to never do the trailing slash redirect for paths with a catch-all at the end. I might actually make that the default behavior, since the current behavior in this case doesn't really make much sense, and I suspect there isn't anyone depending on it working how it does now.

I should be able to get this to you by next week, but maybe earlier. Hope that works :)

That's totally fine. Thanks for taking this on :)

Ended up with a bit of time so I implemented this. Thanks for all your feedback!

Wow, you're fast! This works as imagined. Thank you!
