Hi,
I'm looking for a C#-module that can cache the results of
HTTP-requests persistently on disk. I want to write a program that
fetches data by issuing a number of HTTP-get requests and process the
results. The data will only rarely change, so I would like to use
module that issues proper ETag and If-Modified-Since http-headers to
avoid downloading the data if it hasn't changed.
I haven't been able to find such a module among the standard modules.
Has anyone written such a module?
Regards,
Mattias Holmlund

A full blown managed code solution utilizing the WinINet cache comes
with .NET 2.0.
But you can use those conditional GETs and ETags with HttpWebRequest --
you'll just need to implement your own cache or wrap WinINet.

Thanks for you reply. I'll probably implement my own webcache using
HttpWebRequest then. I only need it to handle simple GET-requests, so
it will be relatively straight-forward.

Hello
Does anybody know how to make FireFox to cache data that comes via
XMLHttpRequest? Here is the issue I deal with:
- On the web server (apache2) I have a static xml file test.xml
- When I download test.xml using XMLHttpRequest, FireFox always gets
complete test.xml from the server, thus not using the browser cache
(apache sends 200 OK back to FireFox).
- If I look into the HTTP request and the HTTP response, I can see
that FireFox...

Hi,
I think this question requires an in depth understanding of how a browser
cache works. I hope I can reach an expert here.
I may have found a quirk in the asp.net documentation or I don't understand
what the SetAllowResponseInBrowserHistory does.
While researching caching I tried the code sample at the following page :

Hi All,
what is the diference between these two cache control header.
no-cache and no-store.
I have read the w3.org explanation.
So lets say I am using only no-cache ....my understanding is that
nothing is cached and nothing is writen to disk.

I am writing an ASP.NET 2.0 application that uses master pages. I have some
pages that must not be cached on the client. In ASP.NET 1.1 I achieved this
using metatags:
<meta http-equiv="Expires" content="0">
<meta http-equiv="Pragma" content="no-cache">
<meta http-equiv="Cache-Control" content="no-cache">
This tags are part of the <headelement. Sample code that I have seen
shows how to add metatags of the form:

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
