Double '/' in URLs causes static content not to load? #663

This static content includes: JavaScript, CSS &etc.

E.g.: http://flask.pocoo.org/docs/patterns// vs. http://flask.pocoo.org/docs/patterns/

If the src attribute is relative to the current page (as it is in the example you're providing) the browser won't be able to get them. Using your example:


The javascript src attributes are like: ../_static/jquery.js

The browser will then use the current url and the src url to try and load:


In the case of 2 slashes:


The browser will combine the 2 into:


Which is incorrect and returns a 404.

This is standard behavior for web browsers, and can be avoided, if you desire, by using more explicit urls for static content.

I think a URL like http://flask.pocoo.org/docs/deploying/////// should 404 in the first place.

apiguy commented Jan 10, 2013

@untitaker I totally agree.

Agreed; make it 404. The double-slash error should be treated as such; i.e.: an error.

Alternatively set a rule which redirects > 1 '/' to 1 '/''

👍 for 404

I am too lazy to reconfigure apache to do that to be honest. :)

Multiple slashes are not squashed into one #21
