es. In other words, any HTTP request message is allowed to contain a message body, and thus must parse messages with that in mind. Server semantics for GET, however, are restricted such that a body, if any, has no semantic meaning to the request. The requirements on parsing are separate from the requirements on method semantics.

So, yes, you can send a body with GET, and no, it is never useful to do so.

An architectural style called REST (Representational State Transfer) advocates that web applications should use HTTP as it was originally envisioned. Lookups should use GET requests. PUT, POST, and DELETE requests should be used for mutation, creation, and deletion respectively.

A URI(Uniform Resource Identifier) can be further classified as a locator, a name, or both.
The term "Uniform Resource Locator" (URL) refers to the subset of URIs that, in addition to identifying a resource, provide a means of locating the resource by describing its primary access mechanism (e.g., its network "location").
The term "Uniform Resource Name" (URN) has been used historically to refer to both URIs under the "urn" scheme [RFC2141], which are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable, and to any other URI with the properties of a name.

There is really no universal maximum URL length. The max length is determined only by what the client browser chooses to support, which varies widely. The 2,083 limit is only present in Internet Explorer (all versions up to 7.0). The max length in Firefox and Safari seems to be unlimited, although instability occurs with URLs reaching around 65,000 characters. Opera seems to have no max URL length whatsoever and doesn't suffer instability at extremely long lengths.

If you want to use the dot renderer. There are alternatives like neato and twopi. If graphiz isn't in your path, figure out where it is installed and run it from there.

You can change the output format by varying the value after -T and choosing an appropriate filename extension after -o.

If you're using windows, check out the installed tool called GVEdit, it makes the whole process slightly easier.

Since the release of pip 10.0, you should be able to fix this permanently just by upgrading pip itself:
***
$ pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org pip setuptools
***
Or by just reinstalling it to get the latest version:

Have you correctly set your PATH to point at your Git installation?
You need to add the following paths to PATH:
***
C:\Program Files\Git\bin\
C:\Program Files\Git\cmd\
***
And check that these paths are correct – you may have Git installed on a different drive, or under Program Files (x86). Correct the paths if necessary.

The syntax is as such: ***set /p variable=[string]***
Once you have set your variable, you can then go about using it in the following fashion.
***
@echo off
set /p UserInputPath=What Directory would you like?
cd C:\%UserInputPath%
***
note the ** %VariableName% ** syntax

Under the SSL tab, I first Imported the Certificate. Then once I selected the Certificate I was able to export as a PFX, both with and without a key file.

1. Use IMG if you intend to have people print your page and you want the image to be included by default.
1. Use IMG (with alt text) when the image has an important semantic meaning, such as a warning icon. This ensures that the meaning of the image can be communicated in all user-agents, including screen readers.
*Pragmatic uses of IMG*
1. Use IMG plus alt attribute if the image is part of the content such as a logo or diagram or person (real person, not stock photo people). —sanchothefat
2. Use IMG if you rely on browser scaling to render an image in proportion to text size.
3. Use IMG for multiple overlay images in IE6.
4. Use IMG with a z-index in order to stretch a background image to fill its entire window.
Note, this is no longer true with CSS3 background-size; see #6 below.
5. Using img instead of background-image can dramatically improve performance of animations over a
background.

*When to use CSS background-image*
1. Use CSS background images if the image is not part of the content. —sanchothefat
2. Use CSS background images when doing image-replacement of text eg. paragraphs/headers. —sanchothefat
3. Use background-image if you intend to have people print your page and you do not want the image to be included by default. —JayTee
4. Use background-image if you need to improve download times, as with CSS sprites.
5. Use background-image if you need for only a portion of the image to be visible, as with CSS sprites.
6. Use background-image with background-size:cover in order to stretch a background image to fill its entire window.

the class is used to hide information intended only for screen readers from the layout of the rendered page.

Screen readers will have trouble with your forms if you don't include a label for every input. For these inline forms, you can hide the labels using the .sr-only class.

Here is an example styling used:
***
.sr-only {
position: absolute;
width: 1px;
height: 1px;
padding: 0;
margin: -1px;
overflow: hidden;
clip: rect(0,0,0,0);
border: 0;
}
***
Is it important or can I remove it? Works fine without.

It's important, don't remove it.

You should always consider screen readers for accessibility purposes. Usage of the class will hide the element anyways, therefore you shouldn't see a visual difference.

SET field_name = REPLACE(field_name , 'oldstring', 'newstring')
WHERE field_name LIKE ('oldstring%');
