This is my header. Notice that I’m using Content-Type with charset=utf-8 and Content-Transfer-Encoding: 8bit . //set all necessary headers $headers = "From: $sender_name<$from>\n"; $headers .= "Reply-To: $sender_name<$from>\n"; $headers

File extensions and MIME Types in .NET

阅读更多关于 File extensions and MIME Types in .NET

问题 I want to get a MIME Content-Type from a given extension (preferably without accessing the physical file). I have seen some questions about this and the methods described to perform this can be resumed in: Use registry information. Use urlmon.dll's FindMimeFromData. Use IIS information. Roll your own MIME mapping function. Based on this table, for example. I've been using no.1 for some time but I realized that the information provided by the registry is not consistent and depends on the

问题 I'm looking for the best (possible on most PHP 5.2 installs and still actively developed) way to detect a files MIME type in PHP.

Is Content-Transfer-Encoding an HTTP header?

阅读更多关于 Is Content-Transfer-Encoding an HTTP header?

问题 I'm writing a web service that returns a base64-encoded PDF file, so my plan is to add two headers to the response: Content-Type: application/pdf Content-Transfer-Encoding: base64 My question is: Is Content-Transfer-Encoding a valid HTTP header? I think it might only be for MIME. If not, how should I craft my HTTP response to represent the fact that I'm returning a base64-encoded PDF? Thanks. EDIT: It looks like HTTP does not support this header. From RFC2616 Section 14: Note: while the

web.xml 加载（解析）顺序

阅读更多关于 web.xml 加载（解析）顺序

web.xml加载顺序应用服务器启动时web.xml加载过程,至于这些节点在xml文件中的前后顺序没有关系,不过有些应用服务器,我曾碰到过的 websphere就严格要求web.xml的节点顺序,否则部署不成功,所以还是赞成按照web.xml标准格式写 content-param --> listener --> filter --> servlet 1、启动WEB项目的时候,应用服务器会去读它的配置文件web.xml.读两个节点:<listener></listener> 和 <context-param></context-param> 2、紧接着,容器创建一个ServletContext(上下文),这个WEB项目所有部分都将共享这个上下文. 3、容器将<context-param></context-param>转化为键值对,并交给ServletContext. 4、容器创建<listener></listener>中的类实例,即创建监听. 5、在监听中会有contextInitialized(ServletContextEvent args)初始化方法,在这个方法中获得： ServletContext = ServletContextEvent.getServletContext(); context-param的值 = ServletContext

How can I find out a file's MIME type (Content-Type)?

阅读更多关于 How can I find out a file's MIME type (Content-Type)?

问题 Is there a way to find out the MIME type (or is it called \"Content-Type\"?) of a file in a Linux bash script? The reason I need it is because ImageShack appears to need it to upload a file, as for some reason it detects the .png file as an application/octet-stream file. I’ve checked the file, and it really is a PNG image: $ cat /1.png ?PNG (with a heap load of random characters) This gives me the error: $ curl -F \"fileupload=@/1.png\" http://www.imageshack.us/upload_api.php <links> <error
