How to hide “page loading”/“transferring data” indicators and spinners caused by loading a (hidden) iframe

阅读更多关于 How to hide “page loading”/“transferring data” indicators and spinners caused by loading a (hidden) iframe

问题 Is there any way to suppress the spinners and "transferring data" indicators that browsers show when a web page is loading? I'm loading a document into a hidden iframe that will take a long time (10's of minutes). I don't want/need the user to be aware of this - it's just confusing to them to have the page look like it's still loading. SO I'd like to be able to disable all of the "page loading" activity that browsers normally show. 回答1: I eventually found a solution that will work for us.

How do disable Transfer-Encoding in Tomcat 6

阅读更多关于 How do disable Transfer-Encoding in Tomcat 6

I have a web application running on Tomcat 6.0.29 server and JDK 1.6. When I send the response to the client, Tomcat sends Transfer-Encoding: chunked in the headers when the response size is > 8KB. For responses < 8KB, it sends Content-Length : I understand that Chunked encoding is the preferred way to handle bulk responses, however our clients do not want to change their code (as it is distributed all across the servers). How can I disable Chunked encoding in Tomcat? I could Disable HTTP/1.1 in Tomcat and enable HTTP/1.0 (not sure how I can do this) I tried the following with no success: In

How do I receive a file upload in spring mvc using both multipart/form and chunked encoding?

阅读更多关于 How do I receive a file upload in spring mvc using both multipart/form and chunked encoding?

I am trying to write a spring mvc method that can receive either a multipart/form or transfer-encoding chunked file upload. I can write a separate method to handle each type but I'd like to do it with the same method so i can use the same REST POST uri such as: http://host:8084/attachments/testupload Here is my best attempt so far: @RequestMapping(value = { "/testupload" }, method = RequestMethod.POST, produces = "application/json") public @ResponseBody ResponseEntity<MessageResponseModel> testUpload( @RequestParam(value = "filedata", required = false) MultipartFile filedata, final

When does Rails respond with 'transfer-encoding' vs. 'content-length'?

阅读更多关于 When does Rails respond with 'transfer-encoding' vs. 'content-length'?

问题 I'm building an API on Rails version 4.1.7/Nginx that responds to request from an iOS app. We're seeing some weird caching on the client and we think it has something to do with a small difference in the response that Rails is sending back. My questions... 1) I want to understand why, for the exact same request (with only the Authorization header value changed), Rails sends back transfer-encoding: chunked sometimes and Content-Length: <number> sometimes? I thought that maybe it had something

Response sent in chunked transfer encoding and indicating errors happening after some data has already been sent

阅读更多关于 Response sent in chunked transfer encoding and indicating errors happening after some data has already been sent

I am sending large amount of data in my response to the client in chunked transfer encoding format. How should I be dealing with any errors that occur midway during writing of the response? I would like to know if there is any HTTP Spec recommended practice regarding this for clients to know that indeed the response is not a successful one but that the server ran into some issue. Once you have started sending the HTTP headers to the client, you can't send anything else. You have to finish sending the response you intended to send, ie the chunked data and associated headers. If an error occurs

Chunked http decoding in java?

阅读更多关于 Chunked http decoding in java?

问题 I am decoding http packets. And I faced a problem that chunk problem. When I get a http packet it has a header and body. When transefer-encoding is chunked I don't know what to do ? Is there a useful API or class for dechunk the data in JAVA ? And if someone , experienced about http decoding , please show me a way how to do this ? 回答1: Use a fullworthy HTTP client like Apache HttpComponents Client or just the Java SE provided java.net.URLConnection (mini tutorial here). Both handles it fully

What are alternatives to NSURLConnection for chunked transfer encoding

阅读更多关于 What are alternatives to NSURLConnection for chunked transfer encoding

问题 I've checked for other questions relevant to this, but the only answer is "Use ASIHTTPRequest " as this is no longer being developed I wanted to ask what alternatives people are using, whilst working on our SDK I came across a lot of strange behaviour in NSURLConnection when receiving data from the server. We tracked it down to the fact that NSURLConnection doesn't deal well with responses in chunked-encoding. Or at least so we read in this question here NSURLConnection and "chunked" transfer

How can I set Transfer-Encoding to chunked, explicitly or implicitly, in an ASP.NET response?

阅读更多关于 How can I set Transfer-Encoding to chunked, explicitly or implicitly, in an ASP.NET response?

问题 Can I simply set the Transfer-Encoding header? Will calling Response.Flush() at some point cause this to occur implicitly? EDIT No, I Cannot call Response.Headers.Add("Transfer-Encoding","anything"); That throws. any other suggestions? Related: Enable Chunked Transfer Encoding in ASP.NET 回答1: TL;DR: Specifying the content-length is the best way to achieve a fast first byte; you'll allow chunking at TCP rather than HTTP level. If you don't know the content-length, setting context.Response

Content-Length header versus chunked encoding

阅读更多关于 Content-Length header versus chunked encoding

I'm trying to weigh the pros and cons of setting the Content-Length HTTP header versus using chunked encoding to return [possibly] large files from my server. One or the other is needed to be compliant with HTTP 1.1 specs using persistent connections. I see the advantage of the Content-Length header being : Download dialogs can show accurate progress bar Client knows upfront if the file may/may not be too large for them to ingest The downside is having to calculate the size before you return the object which isn't always practical and could add to server/database utilization. The downside of
