• Using altered RewriteCond to check if file exists in multiple locations

  - by futuraprime

  I want to use mod-rewrite to check for a file in two separate locations: at the requested URL, and at the requested URL within the "public" directory. Here's what I have so far: RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{DOCUMENT_ROOT}/public/$0 !-f #this line isn't working RewriteRule ^(.*)$ index.php?$1 [L] It can correctly determine if the file is there, but it's not correctly determining if the file is at /public/supplied/file/path/file.extension. How do I test for that?

• Nginx: check content-length before file upload takes place

  - by robw

  I'm trying to prevent users from uploading (accidentally or maliciously) very large files to my website. I have nginx max_client_body_size set to 4M, but if a file larger than this is uploaded, then it uploads the entire file before returning 413 (entity too large). I want to make nginx check the Content-Length header, so that it rejects the request before it's uploaded. Alternatively, a Rails solution would also be acceptable. Any help appreciated.

  - by Callum Rogers

  How do I check the type of a Parameter in an Expression Tree (and get the Expression Tree equivalent of a bool if it the right type)? If it were normal code, I would do this: if(myObj is int) I see there is a Expression.Convert method but this converts the object instead of just checking its type.

• Check for Windsor Container Component Instance

  How can I use my Windsor container to check if an instance (not just a component) has been registered? ie. container.ContainsInstance(typeof(MyType)) [EDIT] Another way of writing this might be Kernel.GetAssignableHandlers(typeof(object)) .Where(handler => handler.Service == typeof(MyType) || handler.ComponentModel.Implementation == typeof(MyType)) .Any(handler => handler.***Instance*** != null) Note that the property Instance doesn't exist in the API. Thanks.
