NET code to compress content. NET content:. All that needs to happen in an ASP. But if you're using an HTTP client in the. So how do you make your client request GZip content? You start by adding an Accept-Encoding header to the request that tells the server to encode responses with GZip. That what the server code above is checking for to decide whether GZip needs to be applied.
The client then receives the compressed response from the server and needs to decomress it. This means the compression can usually be plugged into any Stream interface with no other code changes. It'd be nice if GZip was natively supported by HttpWebRequest, but I suppose this code is easy enough to create a wrapper with. Note that you have to use HttpWebRequest to use GZip encoding - the WebClient class doesn't expose its underlying stream so you can't easily decompress content through that interface.

NET News June 29, Alex O June 29, Gzip is relatively slow as implemented in. NET framework, Deflate is much faster. Plus other implementions of Gzip provide better compression ratios than. NET versions because of patents and such. Rick Strahl June 29, I've actually been using XCeed's compression routines in much of my code, but it's not THAT critical especially in client applications.
I suppose you can control the ordering by doing deflate first instead of GZip in the code I posted above as well. Gopinath V July 06, I'm getting Sys. Common causes for this error are when the response is modified by calls to Response.
Writeresponse filters, HttpModules, or server trace is enabled. Thx, Gopi. Rick Strahl July 13, It's crucial to check whether the browser supports GZip response data and you need to be really careful about caching data in these scenarios as well!

When you run Fiddler on your system, it acts as tiny Web Proxy which sits between your client application and web server. Fiddler only starts capturing traffic when you running it. By default it runs on local machine Curl, Chrome, Internet Explorer. By default when you run Fiddler it behaves as default proxy server on your system. However not all web requests appear in fiddler unless client application using system Default Proxy. Once your web requests appear on left side panel. Simply double click on the request entry to view.
On your Right side you will see two panels. Fiddler comes with another cool feature just like Postman so you can test your API call. Basically there will be a time when you like to edit your request and test with different data e. View text with Syntax Highlighting. Fiddler has another very handy feature call Send to Text Wizard.
Sometimes you like to see difference between two requests. Fiddler comes with very handy feature. Just select two requests and click Diff Option in Right click menu.
For diff to work make sure you install some diff utilities like KDiff3 or WinMerge. When response is compressed then by default you wont be able to see it in Raw tab. When response is compressed you may see header like below in response headers. You can also click on.
Sometimes you want to compare two requests and find the difference. Here is how you can compare requests and re-execute same request or edit it. That means if you running Fiddler and trying to analyze requests made from Curl command line then it wont show up.
Its easy to tell curl that which proxy server to use. Just use -x command line option with proxy server IP and Port e. If you are using aws command line application and want to show requests in Fiddler then add —no-verify-ssl like below.
See below table for each use case.
Base64, URL Encode. Content-Encoding: gzip. Content - Encoding : gzip. Like this: Like LoadingThe same static methods also work in ASP. The first method checks whether the client sending the request includes the accept-encoding for either gzip or deflate, and if if it does it returns true.
The second function uses IsGzipSupported to decide whether it should encode content and uses an Response Filter to do its job. Basically response filters look at the Response output stream as it's written and convert the data flowing through it.
Filters are a bit tricky to work with but the two. However in MVC this sort of thing is typically better handled by an ActionFilter which can be applied with an attribute. So to be all prim and proper I created an CompressContentAttribute ActionFilter that incorporates those two helper methods and which looks like this:. It's basically the same code wrapped into an ActionFilter attribute, which intercepts requests MVC requests to Controller methods and lets you hook up logic before and after the methods have executed.
With the CompressContentAttribute created, it can now be applied to either the controller as a whole:. The former applies compression to every action method, while the latter is selective and only applies it to the individual action method.
Is the attribute better than the static utility function? Not really, but it is the standard MVC way to hook up 'filter' content and that's where others are likely to expect to set options like this. Http compression is very cool and pretty easy to implement in ASP. NET but you have to be careful with it - especially if your content might get transformed or redirected inside of ASP. A good example, is if an error occurs and a compression filter is applied.
NET errors don't clear the filter, but clear the Response headers which results in some nasty garbage because the compressed content now no longer matches the headers. Another issue is Caching, which has to account for all possible ways of compression and non-compression that the content is served. Basically compressed content and caching don't mix well. I wrote about several of these issues in an old blog post and I recommend you take a quick peek before diving into making every bit of output Gzip encoded.
For those curious, here is a version updated for ASP. Dear Rick, Thanks a lot for your post really it is too useful for me. What should i do to handle static compression? Static and Dynamic compression are configured in IIS. If you're using dynamic compression in IIS then you probably don't want to use programmatic compression as well - one or the other. Hi, Is This better way or setting httpCompression in web.
Hamed - depends on what you want to do. If you want to compress all your content the Web.SuperAgent is light-weight progressive ajax API crafted for flexibility, readability, and a low learning curve after being frustrated with many of the existing request APIs.
It also works with Node. The following test documentation was generated with Mocha's "doc" reporter, and directly reflects the test suite. This provides an additional source of documentation. A request can be initiated by invoking the appropriate method on the request object, then calling. For example a simple GET request:. Old-style callbacks are also supported, but not recommended. Instead of. Absolute URLs can be used.
The Node client supports making requests to Unix Domain Sockets :. You can also use the. The following example is equivalent to the previous. SuperAgent formats are extensible, however by default "json" and "form" are supported.
Sending a FormData object is also supported. As a short-hand the. You can setup automatic serialization for other types as well:. If you want to send the payload in a custom format, you can replace the built-in serialization with the.
When given the. This method has two optional arguments: number of retries default 3 and a callback. It calls callback err, res before each retry. In a similar fashion to the. Which references request. You can do this with either req.
See issue for details. For example populating? By default the query string is not assembled in any particular order. An asciibetically-sorted query string can be enabled with req.

I needed to gzip all the json responses in our app because of the large amount of data we have. Any browser already unzips automatically the received response into JSON.
How do I make Postman unzip this automatically? Is this possible at all? Sorry that I did not put any feedback here. I was doing the compression manually while Vert.
So Postman maybe found a double-gzipped response and could therefore not unzip it. When I use only the gzip feature of Vert. PS: please please mark this as solved or not applicable. Thanks :. If it's just the value that's messed up, it could be one or more of. For the first 2, you'd have to change it within the server - and also it's really probable that you'll end up having the same problem with some of the available JSON encoding libraries for whichever language you're using.
For the latter 3, you'd have to try scripting something in the Tests code to treat the received value, but if it's really compressed, I'm not sure if Postman exposes any libraries that are able to treat this. Facing a similar trouble, my express server is doing a gzip for my code. Any help madebysid? Postman unzips and displays it for debugging purposes.
You won't get a zip file downloaded. If you really need to test it that way, have a cURL request. Skip to content.

Server Fault is a question and answer site for system and network administrators. It only takes a minute to sign up. I see lots of information about enabling http compression for server responses but what about for incoming requests. Wouldn't it make sense for the browsers to compress large form posts before sending them to the server? Another example is a REST web service that we use.
So is this a solved problem on the server side or does each web application have to handle it individually? To PUT data to the server compressed you must compress the request body and set the Content-Encoding: gzip header.
The header itself must be uncompressed. Now if a request contains a Content-Encoding: gzip header, the body will be automatically decompressed. Few browsers have the ability to gzip request bodies. However, some special applications actually do support request compression, for instance some WebDAV clients. And an article describing it is here :.
So how do you do it? This means that the whole body of the request must be gzip compressed if we chose to use this, it is not possible to compress only the part containing the file for example in a multipart request.
Separately, a browser can request server response content to be compressed by setting Accept-Encoding header as per here :.How to send and capture API requests using Postman
Answering the part about compressed requests, not responses: yes, it is possible, even if it does not seem in widespread usage. The client-side app needs to set the appropriate content-encoding header. As for the server-side app, there are 2 choices:. An example library which can do this is the phpxmlrpc one. This is possible using f. Not natively from any browser I know of, you'd have to find a plugin that would do it for you.
You basically have to set the content-encoding HTTP header to let the server know how the request is coming in. The server, of course, needs to be able to handle that encoding. This is NOT allowed. According to the HTTP specification RFCContent-Encoding is NOT one of the possible request header fields, therefore it is not possible to compress the request entity body as there is no legal way to let the server know this has occurred.
Any compression of the request body is done only as a non-standard extension. Sign up to join this community. The best answers are voted up and rise to the top. Home Questions Tags Users Unanswered.
