Let's suppose you're building your shiny new Orchard Core website. In there you're also building a shiny new page, with Flow Part obviously. You throw together a lot of widgets to get all the bells and whistles on the page, then you save it and BAM! Internal Server Error: "InvalidDataException: Form value count limit 1024 exceeded." What's this, did I break Orchard? Is Orchard trying to break me? Let's fix this! The exception happens because the structure you've built with Flow Part is simply too large for the default ASP.NET Core limits. This is not something that would be too extreme to achieve, actually: If you have more complex widgets (with a lot of fields each) and you put several of them into a complex nested structure you can quite possibly build something by hand that would fail like this. Ask how I know! You can increase the limits restricting posted form value sizes, and in this particular case you'd need to change the ValueCountLimit value of FormOptions. Put this into the Startup class of your Orchard-based web app project (it won't work in a module or theme!): services.Configure This increased the limit to 4096, plenty more than the default. However, keep in mind that these limits have their uses: Malicious users could try to post large pieces of data to your server, trying to overwhelm it for example. So only increase this as much you only need! Note BTW that we're using the ASP.NET Core configuration API here, something which is also demonstrated in detail in our Training Demo Module, so follow up learning there! Did you like this post?

So you're building a localized Orchard Core site and want all URLs to be in the form of /culture-name/rest/of/the/url, e.g. /hu-HU/my-page. (Figure out what "hu-HU" is! Hint: It's not an owl, neither a rock band from Mongolia!) What do you need to achieve this? Well, we've already seen how to localize content items to achieve this, but that's just for content pages. There is one small piece missing though: How to get the same functionality for controller actions, i.e. coded pages? There is nothing built into Orchard Core for this, actually. And the reason is that all you need is available in ASP.NET Core MVC already. First, you'll need to set up RouteDataRequestCultureProvider so the URL segment indicating the culture will be used to set the culture of the current request. Just add this to your module's or theme's Startup class (if you don't yet know how to build a module, check out our Training Demo!): services.Configure So far so good. Next, you'll need the controller actions you want to be culture-aware to be routed in a way that the culture name is included in the URL: public class CultureAwareController : Controller { [Route("{culture}/culture-aware"] public ActionResult CultureAwareAction() { // Build the result here. } } So now you'll be able to reach this action from under /hu-HU/culture-aware for example. There's one final part missing: Building URLs for these actions. This is quite simple too, you'd e.g. create a link for this action like following: <a asp-action="CultureAwareAction" asp-controller="CultureAware" asp-area="CultureAwareModule" asp-all-route-data="routeParams">Click here</a> That's it! Of course, this can get more complex. You can make route configuration as well as URL generation easier by centralizing this culture parameter handling, which is useful if you have loads of such controllers and links.

Every website needs a favicon of course and you can easily add one to your Orchard Core site from a theme or module with a link tag in a template. However, there's a catch: Certain browsers will still search for it (as a first attempt) under the path /favicon.ico. This can be a tiny bit detrimental to the client-side performance, and show up as annoying errors in your logs. So what can you do to serve a favicon under that path too? You could do e.g. the following: Add an actual file to your web project's wwwroot folder directly. This will work but you'll most likely have more than one icon for the site, and you'll keep them in a theme. So having two places with icons is less than ideal. Serve the same file that you have in your theme with a middleware or something. Doable but you'd teach the affected browsers that what they're doing is actually acceptable :). Redirect a /favicon.ico request to the actual favicon. This is what we'll do with the code snippet below! Open up your theme's Startup class and add this to its Configure() method (or add the method first if you haven't used it otherwise): public override void Configure(IApplicationBuilder app, IEndpointRouteBuilder routes, IServiceProvider serviceProvider) => app.Map("/favicon.ico", appBuilder => appBuilder.Run(context => { context.Response.Redirect("/My.Theme/favicon.ico", true); return Task.CompletedTask; })); As you can see this simple snippet will listen on the /favicon.ico path and redirect the client to the favicon you have in your theme (in this case we assumed it's in the root of your theme's wwwroot folder but of course it can be in any subfolder).
