Apache Storm Interview Questions And Answers

Does Apache act as a Proxy server?

Yes, It acts as proxy also by using the mod_proxy module.

What is multiviews?

A MultiViews search is enabled by the MultiViews Options. If the server receives a request for /some/dir/foo and/some/dir/foo does not exist, then the server reads the directory looking for all files named foo.*, and effectively fakes up a type map which names all those files, assigning them the same media types and content-encodings it would have if the client had asked for one of them by name. It
then chooses the best match to the client’s requirements,and returns that document.

Does Apache include a search engine?

Yes, Apache contain a Search engine. You can search a report name in Apache by using the “Search

Why does not Apache include SSL?

SSL (Secure Socket Layer) data transport requires encryption, and many governments have restrictions upon the import, export, and use of encryption technology.

If Apache included SSL in the base package, its distribution would involve all sorts of legal and
bureaucratic issues, and it would no longer be freely available.

Also, some of the technology required to talk to current clients using SSL is patented by RSA Data Security, who restricts its use without a license.

Does Apache include any sort of database integration?

No. Apache is a Web (HTTP) server, not an application server. The base package does not include any such functionality. See the PHP project and the mod_perl project for examples of modules that allow you to work with databases from within the Apache environment.
