$filter: The expression specified with $filter is evaluated for each resource in the collection, and only items where the expression evaluates to true are included in the response.

serviceRoot/People?$filter=FirstName eq 'Scott'

$orderby: The $orderby system query option allows clients to request resources in either ascending order using asc or descending order using desc.

serviceRoot/People('scottketchum')/Trips?$orderby=EndsAt desc

$count: The $count system query option allows clients to request a count of the matching resources included with the resources in the response.

serviceRoot/People/$count

$select: The $select system query option allows the clients to requests a limited set of properties for each entity

serviceRoot/Airports?$select=Name, IcaoCode

$top & $skip: The $top system query option requests the number of items in the queried collection to be included in the result. The $skip query option requests the number of items in the queried collection that are to be skipped and not included in the result.

serviceRoot/People?$top=2

$expand: The $expand system query option specifies the related resources to be included in line with retrieved resources.

serviceRoot/People('keithpinckney')?$expand=Friends

Supporting multiple filters:

Use the and/or operators to apply multiple filters.

Marks a test method as being a data theory.

Data theories are tests which are fed various bits of data from a data source, mapping to parameters on the test method.

If the data source contains multiple rows, then the test method is executed multiple times (once with each data row). Data is provided by attributes which derive from Xunit.Sdk.DataAttribute:

• Xunit.InlineDataAttribute
• Xunit.MemberDataAttribute

The Content-Disposition response-header field has been proposed as a means for the origin server to suggest a default filename if the user requests that the content is saved to a file.

Example:

Content-Disposition: attachment; filename="fname.csv"

Note: In the context of a CORS request, use the Access-Control-Expose-Headers Http header to expose Content-Disposition as a header value.

References:

https://www.w3.org/Protocols/rfc2616/rfc2616-sec19.html

All CORS related headers are prefixed with "Access-Control-".

Access-Control-Allow-Origin
Access-Control-Allow-Credentials
Access-Control-Expose-Headers

Security information and event management (SIEM) software products and services combine security information management (SIM) and security event management (SEM). They provide real-time analysis of security alerts generated by applications and network hardware.

Vendors sell SIEM as software, as appliances or as managed services; these products are also used to log security data and generate reports for compliance purposes.

package-lock.json is automatically generated for any operations where npm modifies either the node_modules tree, or package.json.

It describes the exact tree that was generated, such that subsequent installs are able to generate identical trees, regardless of intermediate dependency updates.

This file is intended to be committed into source repositories, and serves various purposes:

• Describe a single representation of a dependency tree such that teammates, deployments, and continuous integration are guaranteed to install exactly the same dependencies.
• Provide a facility for users to "time-travel" to previous states of node_modules without having to commit the directory itself.
• To facilitate greater visibility of tree changes through readable source control diffs.
• And optimize the installation process by allowing npm to skip repeated metadata resolutions for previously-installed packages.

Once you're in a Vim editor:

1. Type 'i' to switch to 'insert' mode. Modify the file now.
2. Hit 'esc' to return to the 'normal' mode
3. Type ':wq' - w - 'write' and q - 'quit'

The 'normal' mode of a Vim editor: all key presses are interpretted as a command. To get into an editing (ie insert) mode, press 'i'
