This feature allows admins to set a specific quota for each user, in MiB. This feature is particularly useful for shared instances, where unlimited user storage might be unfeasible or even dangerous for the server. Also, a nice HTML5 <progress> element has been added to the site that shows how much of the quota has been consumed. If no quota is set, slcl falls back to the default behaviour i.e., assume unlimited storage. Limitations: - While HTTP does specify a Content-Length, which determines the length of the whole request, it does not specify how many files are involved or their individual sizes. - Because of this, if multiple files are uploaded simultaneously, the whole request would be dropped if user quota is exceeded, even if not all files exceeded it. - Also, Content-Length adds the length of some HTTP boilerplate (e.g.: boundaries), but slcl must rely on this before accepting the whole request. In other words, this means some requests might be rejected by slcl because of the extra bytes caused by such boilerplate. - When the quota is exceeded, slcl must close the connection so that the rest of the transfer is cancelled. Unfortunately, this means no HTML can be sent back to the customer to inform about the situation.
