Data cached in web service?

BVM
Hi,

I have a problem and hope you can give some advice.

I have a windows Form which uses web service to communicate with our web site and database. It's working fine in most of our offices. However one of our offices use VPN(virtual private network) to do their work. They often(not always) get error when they use the form. I look at into it and found that no matter how they change the date range, the query results are always the same. If they donot use the form for sevral days, it will work again. If they use it again in the same day, then the error will come up. It sounds data are cached somewhere in the network or in their computer. Do you know where the data cached and how to prevent this?

I am using HP laptops and servers.

Thanks,

Dennis Huang

I'm caching data in the Application object to speed up certain pages on a website The main reason is that the retrieval of this data takes quite a while (a few seconds) and fetching the same data from the "cache" hardly takes any time A basic pattern used to get the data from disk, or from cache is this data = getDataFromCache("mydata" if data = "" the data = getDataFromDisk( storeDataInCache(data, "mydata" end i

I build a system where a Windows service iterates through a file and sends each line in the file as a record to a database, by calling a web service asynchronously. It runs on a w2k server. What I notice is: When the web service gets called, there seems to be a slowness and potential for missed calls - my guess is because it's being moved into memory. This causes problems as records are dropped. My solution is to redo the load...

I am new to web services and want to expose a C# program through web services (soap or otherwise) that will have a service with cached data running on a server that clients can make requests to without instanciating the (data) classes locally. I see many examples of using web services where the server really just handles requests to point to XML serialized classes that have to be instanciated locally on the client. This is no good for me...

Is it advisable to store my own data as XML in the folder returned by HttpRuntime.CodeGenDir? (i.e. in "Temporary ASP.NET Files") Each web service on the server must try to read its own cached file when it (re)starts. If it 's not present, it retrieves it from a remote service and caches it locally. If it's not advisable, what is the "best practice" for caching global

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. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...
