-  <p>XMPP protocol extensions already define methods for peer-to-peer file transfer such as &xep0096; or &xep0234; however due to their very nature of being peer-to-peer they don't work very well in scenarios where it is requeried to send a file to multiple receipients or multiple resources of the same receipient  at once. They also don’t work alongside offline storage, MUC history and &xep0313;.</p>

-  <p>Uploading files manually to an HTTP server and sharing the link has been a workaround for this for a long time now. While users have a variety of services to choose from the downside of this manual approach is that an XMPP client can not automate this process on behalf of the user since these services don’t share a common api. Furthermore using a third party service would probably require the user to enter addional credentials into their XMPP client specifically for the file upload.</p>

   <p>This XEP defines an approach to request permissions from another entity to upload a file to a specific path on an HTTP server and at the same time receive an URL from which that file can later be downloaded again. These tuples consisting of a PUT and a GET-URL are called slots.</p>

   <ul>
     <li>Be as easy to implement as possible. This is grounded on the idea that most programming languages already have HTTP libraries available.</li>
-    <li>Be agnostic toward the distributon of the actual URL. Users can choose to send the URL in the body of a message stanza, utilize &xep0066; or even use it as their avatar in &xep0084;</li>

-    <li>Do not provide any kind of access control or security beyond Transport Layer Security in form of HTTPS and long random pathes that are impossible to guess. That means everyone who knows the URL SHOULD be able to access it.</li>

-  <p>An entity advertises support for this protocol by including the "urn:xmpp:http:upload" in its service discovery information features as specified in &xep0030; or section 6.3 of &xep0115;. To avoid unnecessary round trips an entity SHOULD also include the maximum file size as specified in &xep0128; if such a limitation exisits. The field name MUST be "max-file-size" and the value MUST be in bytes.</p>

 <section1 topic='Upload' anchor='upload'>
-  <p>The actual upload of the file happens via HTTP-PUT and is out of scope of this document. The upload service MUST reject the file upload if the Content-Length does not match the size of the slot request. The service SHOULD reject the file if the Content-Type has been specified beforehand and does not match. The service MAY assume application/octet-stream as a Content-Type if it the client did not specficy a Content-Type at all.</p>

   <p>There is no further XMPP communication required between the upload service and the client. A HTTP status Code of 201 means that the server is now ready to serve the file via the provided GET URL. If the upload fails for whatever reasons the client MAY request a new slot.</p>

 <section1 topic='Implementation Notes' anchor='impl'>
-  <p>The upload service SHOULD choose an appropriate timeout for the validity of the PUT URL. Since there is no reason for a client to wait between requesting the slot and starting the upload relativly low time out values of around 60s are RECOMENDED.</p>

   <p>It is RECOMMENDED that the service stores the files for as long as possible which is of course limited by storage capacity. A service MAY choose to store the latest x MiB of a given user.</p>

   <ul>
   <li>Client implementors MUST consider the fact that without additional end-to-end-encryption files uploaded to a service described in this document will store those files in plain text on that service. Client implementors SHOULD either use this only for semi public files (for example files shared in a public MUC or a PEP Avatar) or implement appropriate end-to-end encryption.</li>
   <li>Service implementors SHOULD use long randomized parts in their URLs making it impossible to guess the location of arbitrary files</li>
-  <li>Server operators SHOULD consider the responsibilty that comes with storing user data and MAY consider appropriate measures such as full disk encryption.</li>
