Why to use/not to use Server.Transfer

By
Care sunt avantajele/dezavantajele folosirii Server.Transfer in loc de Resposese.Redirect?
Server.Transfer nu trimite la brower un mesaj prin care ii spune sa incarce o alta pagina. Din aceasta cauza nu se mai face un drum pana la client pentru a face redirectarea. Prin acest mecanism serverul nu mai trebuie sa rezolve atatea cereri HTTP. Trebuie avut grija deoarece Server.Transfer pastreaza URL original la client. Cea ce poate sa ne induca in eroare la debug sau daca vrem sa facem SEO. Daca vrem sa redirectam userul spre o pagina externa( de exemplu www.google.ro), atunci Server.Transfer nu o sa poate sa fie folosit.
Server.Transfer are un parametru optional denumit “preserverForm”, care daca este setat pe TRUE, query-ul string-ului si toate variabilele din forma sunt trimise mai departe. Exista un bug care apare uneori cand vrem sa transferam aceste valori. Pentru a evita aceast bug putem sa setam "enableViewStateMac" pe TRUE pe pagina spre care facem redirectare.

    Eu as evita pe cat posibil Server.Transfer sau Server.Execute, cand se poate - sunt niste mosteniri din ASP "clasic" care vin cut tot felul de "gothchas" la pachet.. :)

How to audit an Azure Cosmos DB

By
In this post, we will talk about how we can audit an Azure Cosmos DB database. Before jumping into the problem let us define the business requirement: As an Administrator I want to be able to audit all changes that were done to specific collection inside my Azure Cosmos DB. The requirement is simple, but can be a little tricky to implement fully. First of all when you are using Azure Cosmos DB or any other storage solution there are 99% odds that you’ll have more than one system that writes data to it. This means that you have or not have control on the systems that are doing any create/update/delete operations. Solution 1: Diagnostic Logs Cosmos DB allows us activate diagnostics logs and stream the output a storage account for achieving to other systems like Event Hub or Log Analytics. This would allow us to have information related to who, when, what, response code and how the access operation to our Cosmos DB was done. Beside this there is a field that specifies what was th...

Can User Technical Profile Influence AI Architecture Decisions?

By
In the last few days, I ran a small experiment on Devin/Windsurf/Cascade, BMAD, and LLM-based architecture decisions. The initial concern was simple: if an AI coding assistant knows something about the user, for example, that the user is a Java developer or a .NET developer, can this information influence the architecture and technology stack that the AI will propose? This question is important because many companies are starting to use AI tools not only for coding but also for product discovery, architecture, documentation, and technical decision-making. If the AI is influenced by the developer's personal profile, the result may not be fully neutral. It may look like a business or architecture decision, but in reality, it may be partially shaped by the context of the person using the tool. The test was done using BMAD with Devin/Windsurf/Cascade. The scenario was a unified field service operations platform. The task was to let BMAD refine the product, define the architecture and s...

ADO.NET provider with invariant name 'System.Data.SqlClient' could not be loaded

By
Today blog post will be started with the following error when running DB tests on the CI machine: threw exception: System.InvalidOperationException: The Entity Framework provider type 'System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer' registered in the application config file for the ADO.NET provider with invariant name 'System.Data.SqlClient' could not be loaded. Make sure that the assembly-qualified name is used and that the assembly is available to the running application. See http://go.microsoft.com/fwlink/?LinkId=260882 for more information. at System.Data.Entity.Infrastructure.DependencyResolution.ProviderServicesFactory.GetInstance(String providerTypeName, String providerInvariantName) This error happened only on the Continuous Integration machine. On the devs machines, everything has fine. The classic problem – on my machine it’s working. The CI has the following configuration: TeamCity .NET 4.51 EF 6.0.2 VS2013 It see...
