This also allows the Web browser to enable the user to know the recommended file format for the attached.octet-stream file.These OCTET-STREAM files may be opened by renaming the extension of the attached file to a specific file extension, and then by using an application with support for opening such files. For example, an.octet-stream file. Octet-stream files are usually executable application files. If still having trouble opening a file, request that the sender attempt to retransmit the file. Email or web clients are rarely able to open octet stream files, but may be able to determine the appropriate program to open the file.
Any general, binary format that the server doesn't recognize usually uses this MIME type. Upon receiving this type, most browsers prompt the user and give the user an option to save to disk. RFC1521, Borenstein |

What Are MIME Types?
A Multi-Purpose Internet Mail Extension (eg. “application/octet-stream”), also known as a MIME, is type of Internet standard originally developed to allow the exchange of different types of data files through e-mail messages. MIME types like application/octet-stream are classified into specific data categories such as Video, Audio, Image, and many more. https://jrgenerous220.weebly.com/microsoft-dynamics-rms-pos.html. This categorization provides instructions to your computer or mobile device about how these files should be opened / viewed.
Why Do I Need MIME Types Like application/octet-stream?
Categorizing MIME types like application/octet-stream into a data type such as “Application” allows your e-mail client or Internet browser to display the content as intended. For example, when you attach a digital camera photo file to an e-mail, an Image MIME type will be associated with that file to allow your recipient to view the photograph.
Here's how it works: Web servers (computers that host websites and e-mail) insert a set of MIME instructions into the beginning of a data transmission, such as an e-mail message or webpage, in the following format:
Content-Type: application/octet-stream
[Format Explanation: The MIME type, which in this example is “Application”, is separated by a forward slash (“/”) and followed by a subtype.]
This set of instructions tells your client application, such as an e-mail program (eg. Microsoft Outlook, Apple Mail) or web browser (eg. Google Chrome, Mozilla Firefox), which “player application” should be used to properly display the application/octet-stream content.
Many modern web browsers include built-in components to display common data types such as image players (eg. GIF, JPEG), Adobe Flash Player, Javascript, and many more. Other less-common types of players must be downloaded separately in order to properly display the MIME content.
What Are The Most Common Problems Associated With application/octet-stream?
Sometimes you’ll find that your web browser or e-mail client is unable to properly display your application/octet-stream content. This could be due to one of two reasons:
1. You are missing the proper Application “player software” to display the application/octet-stream content.
2. Your Windows Registry contains an incorrect file extension (eg. XLS, PDF) association with the application/octet-stream MIME type.
How To Fix application/octet-stream Issues
Do I have the application/octet-stream “player application” installed?
The first step in troubleshooting issues with opening application/octet-stream content is to first make sure that you have the correct “player application” installed for this MIME type. Because there can be several (or even hundreds) of related software applications to application/octet-stream, it is very difficult for us to compile a comprehensive list.
Therefore, a key strategy in determining the correct application is to look for clues on what software programs might be related to application/octet-stream. Seaworld adventure tycoon 2 download. Look at the naming of the subtype for clues about a related program (eg. Word, Excel) or software developer name (eg. Microsoft).
Furthermore, if you’ve been sent MIME type application/octet-stream as an e-mail attachment, look for the file extension of the attached file. This file extension (eg. PKG, LHA, LZH, etc.) can provide you with a clue of what “player application” is associated with this Application MIME. Take a look at our file extension list below to see if there are any clues to finding the right “player application”.
Do I have broken application/octet-stream file associations?
The second step in troubleshooting application/octet-stream issues is making sure that you have correct file associations in the Windows Registry. Installing and uninstalling programs can lead to incorrect file associations with application/octet-stream. Take a look at your Windows Registry settings to ensure that the MIME type is correctly associated with the “player application” and file extension.
WARNING: DO NOT edit the Windows Registry unless you are an advanced computer user with experience editing the Registry. Making an error in editing the Registry can create irreversible damage to your PC.
If you are not comfortable editing the Windows Registry, we highly recommend using an automated registry cleaning program, or taking you computer to a qualified professional. Ecg made simple pdf.

The HTTP standard says:
If this header [Content-Disposition: attachment] is used in a response with the application/octet-stream content-type, the implied suggestion is that the user agent should not display the response, but directly enter a `save response as..' dialog.
I read that as
But I would have thought that
Content-Type
would be application/pdf
, image/png
, etc.Should I have
Content-Type: application/octet-stream
if I want browsers to download the file?Paul Draper

No.
The content-type should be whatever it is known to be, if you know it.
application/octet-stream
is defined as 'arbitrary binary data' in RFC 2046, and there's a definite overlap here of it being appropriate for entities whose sole intended purpose is to be saved to disk, and from that point on be outside of anything 'webby'. Or to look at it from another direction; the only thing one can safely do with application/octet-stream is to save it to file and hope someone else knows what it's for.You can combine the use of
Content-Disposition
with other content-types, such as image/png
or even text/html
to indicate you want saving rather than display. It used to be the case that some browsers would ignore it in the case of text/html
but I think this was some long time ago at this point (and I'm going to bed soon so I'm not going to start testing a whole bunch of browsers right now; maybe later).RFC 2616 also mentions the possibility of extension tokens, and these days most browsers recognise
inline
to mean you do want the entity displayed if possible (that is, if it's a type the browser knows how to display, otherwise it's got no choice in the matter). This is of course the default behaviour anyway, but it means that you can include the filename
part of the header, which browsers will use (perhaps with some adjustment so file-extensions match local system norms for the content-type in question, perhaps not) as the suggestion if the user tries to save.Hence:
Means 'I don't know what the hell this is. Please save it as a file, preferably named picture.png'.
Means 'This is a PNG image. Please save it as a file, preferably named picture.png'.
Means 'This is a PNG image. Please display it unless you don't know how to display PNG images. Otherwise, or if the user chooses to save it, we recommend the name picture.png for the file you save it as'.
Of those browsers that recognise
inline
some would always use it, while others would use it if the user had selected 'save link as' but not if they'd selected 'save' while viewing (or at least IE used to be like that, it may have changed some years ago).Application/octet-stream
