Why the 609 Certification is Important

The Clean Air Act of 1990 requires auto technicians to be certified in handling refrigerants. Properly disposing of refrigerants helps protect people and the environment from harm. Without correctly recovering and recycling refrigerant, dangerous health risks are posed to humans and the global climate. An EPA 609 Certification allows industry professionals to understand and stay compliant with EPA guidelines in handling and disposing of refrigerants.

What to expect in 609 Certification & Testing Process

Before taking the EPA 609 Certification test, MACS strongly recommends industry professionals completely review the Section 609 Study Guide. Further prepare by viewing MACS’ Section 609 webinar, a recorded training class available for only $25.

When the Section 609 Study Guide and/or webinar has been reviewed, choose from an at-home or online 609 Certification test in English or Spanish. The test is open book with 25 multiple-choice questions. There is also a FREE 10-question practice exam available online. (only)

When an HTTP client (generally a web browser) requests a URL that points to a directory structure instead of an actual web page within the directory, the web server will generally serve a default page, which is often referred to as a main or 'index' page.

A common filename for such a page is index.html, but most modern HTTP servers offer a configurable list of filenames that the server can use as an index. If a server is configured to support server-side scripting, the list will usually include entries allowing dynamic content to be used as the index page (e.g. index.php, index.shtml, index.jsp, default.asp) even though it may be more appropriate to still specify the HTML output (index.html.php or index.html.aspx), as this should not be taken for granted. An example is the popular open source web server Apache, where the list of filenames is controlled by the DirectoryIndex^[1] directive in the main server configuration file or in the configuration file for that directory. It is possible to make do without file extensions at all, and be neutral to content delivery methods, and set the server to automatically pick the best file through content negotiation.

If the server is unable to find a file with any of the names listed in its configuration, it may either return an error (generally 404 Not Found) or generate its own index page listing the files in the directory. It may also return a 403 Index Listing Forbidden. Usually this option is also configurable.

History[edit]

A scheme where web server serves a default file on per-subdirectory basis has been supported as early as NCSA HTTPd 0.3beta (22 April 1993),^[2] which defaults to serve index.html file in the directory.^[2][3] This scheme has been then adopted by CERN HTTPd since at least 2.17beta (5 April 1994), which its default supports Welcome.html and welcome.html in addition to the NCSA-originated index.html.^[4]

S.a.c. Mac Os Update

Later web servers typically support this default file scheme in one form or another; this is usually configurable, with index.html being one of the default file names.^[5][6][7]

Implementation[edit]

In some cases, the home page of a website can be a menu of language options for large sites that use geo targeting. It is also possible to avoid this step, for example by using content negotiation.

In cases where no index.html exists within a given directory, the web server may be configured to provide an automatically-generated listing of the files within the directory instead. With the Apache web server, for example, this behavior is provided by the mod_autoindex module^[8] and controlled by the Options +Indexes directive^[9] in the web server configuration files.
