Templates and 404 page

Question

How can I create 404 page and apply it all across the website? Is that something I need to add in Application.cfc ?

I have 404.cfc page which contains only gif, however if I would to navigate to that page, all templates are being loaded (header with navigation), body and even footer. Can I somehow disable templates for this page?

Even without this code, the samecode is being shown, so it had no difference. Yes, I am getting the same result with .cfm or without .cfm. In the code I have shown above, how can I redirect to page 404.cfm I have already prepared? With no templates being loaded. Right now I am getting this default 404 page not found page..

As follows:

Comment out the onMissingTemplate function in Application.cfc.
Use the suggestion I gave at the beginning: "First way: via the ColdFusion Administrator".
If you are using IIS and want to avoid IIS's custom 404 pages, there is something extra
you will have to do:
- Open the file {CF_INSTANCE}\config\wsconfig\{magic_number}\isapi_redirect.properties.
- Add the property iis_skip_custom_errors_enable=true
(Refer to the following documentation, and scroll to the bottom of the page: https://helpx.adobe.com/coldfusion/cfml-reference/application-cfc-reference/onmissingtemplate.html)

You don't need to solve the 404, or "missing-template", problem. That is because ColdFusion has solved it for you! In fact, versions since ColdFusion 9 have solved the problem in at least 2 ways:First way: via the ColdFusion AdministratorGo to the Server Settings page of the ColdFusion Administrator. There you will see a section for Missing Template Handler. In the input field, specify the relative path to the template that you want ColdFusion to execute when it cannot find a requested template. [Notes: (1) This setting applies to missing templates server-wide. (2) "Relative path" means a path relative to the web root. For example, my handler file is C:\ColdFusion2023\cfusion\wwwroot\workspace\missingTemplate\missing.cfm. So I specify the path \workspace\missingTemplate\missing.cfm. (3) You probably want to include a 404 header in the page. For example, I did so by including the following line of code in the page missing.cfm: ] Second way: via Application.cfcInclude the onMissingTemplate event-handler in Application.cfc. An example adapted from Adobe's documentation on onMissingTemplate is:

#listLast(Arguments.targetPage,"/")# could not be found.

You requested a non-existent ColdFusion page. Please check the URL.

function onMissingTemplate(string targetPage) {// Log all errors. cflog( text="Missing template: #Arguments.targetPage#", file="missing-pages", type="error" );cfheader( statustext="Not Found", statuscode=404 );// Display an error message. writeOutput("

#listLast(Arguments.targetPage,'/')# could not be found.

You requested a non-existent ColdFusion page. Please check the URL.

");return true;}Note that I have included the 404 header.The second method takes precedence over the first. So, if you implement both the Administrator and Applicatiion.cfc missing-template handlers, ColdFusion will only run the Application.cfc one.
