I have an ASP.Net site (happens to be MVC, but that's not relevant here) with a few pages I'd like cached really well. Specifically I'd like to achieve: output cached on the server for 2 hours. if the file content on the server changes, that output cache should be flushed for that page cached in the browser for 10 minutes (i.e. don't...

I would like to get a glimpse of web-sites created for iPhone devices. In order to be able to view those sites I have to modify the User-agent header in the HTTP request that my browser sends. That way I can trick the web-server into believing that my browser is an iPhone browser, and then the web-server would send my the iPhone version ...
I can't seem to figure out how to add headers to my restlet response. When I look at the available methods in the Response object, all I see is setStatus, setEntity, and setAttributes but none of these tell me how to set custom http headers on the response.

I'm using PHP to create a CSV file from a database query. I run the query, set the headers, and load the page up in Firefox and the file promps for download and opens in excel just like it's supposed to.

Is there a way to detect in my script whether the request is coming from normal web browser or some script executing curl. I can see the headers and can distinguish with "User-Agent and other few headers" but in curl fake headers can be set, so i am not able to track the request. Please suggest me ways about identifying the curl or othe...

Is it possible to set HTTP headers for an XmlListModel in QML? Suppose you want to use an XML feed which requires an API key as the data source for a list model. I can pass the API key as an URL attribute, but it would be more elegant to pass it in the HTTP headers. I didn't find anything in the documentation about this. Is it possible t...

If I want to politely refuse service on a web site due to temporary overload, the HTTP response 503 Service Unavailable seems appropriate. The spec mentions sending a Retry-after header with the 503. Is there any point? Does Retry-after affect anything? Do browsers pay any attention to it? ...

Is it OK to return a 301 / 302 / 303 code when returning an image resource? I have done this in the past and it seems to work. Is it good practice and is it compatible with most browsers? ...
I'd like an HTTP response to expire 24 hours from now (meaning the browser won't make any requests for that URL until tomorrow). But, if the request is re-issued tomorrow after expiration, I want to make sure the browser will send the right request headers so that the server will send a 304 instead of forcing the client to re-download th...
When you write some binary data in the http response stream (of Servlet etc) or using the Content-disposition header, what is the factor that determines whether the downloaded file is saved as readonly or has write permissions ? How can we control whether to make it read-only or not? Is that browser/OS dependant? ...
Why/when does one has to use CRLF's at the end of header in PHP?

What I'd like to do is find out what is the last/final URL after following the redirections. I would prefer not to use cURL. I would like to stick with pure PHP (stream wrappers). Right now I have a URL (let's say http://domain.test), and I use get_headers() to get specific headers from that page. get_headers will also return multiple ...
