## Basic calculation of differential in Lie group

I get an unexpected result (for me) when performing the following calculation. If someone could point out a flaw, or maybe give some intuition, I would be grateful.

Leave $$a (t)$$ Be a smooth curve in a Lie group. Sun. Then for an arbitrary smooth function F in G;

$$(T_ {a (t)} L_ {a ^ {- 1} (t)} point {a} (t)) f = point {a} (t) (f circ L_ {a ^ { -1} (t)}) = left. frac {d} {ds} right | _ {t} (f circ L_ {a ^ {- 1} (s)} circ a (s)) = left. frac {d} {ds} right | _ {t} f (e) = 0.$$

I suspect that a problem may be that $$X (g): g mapsto T_ {a (t)} L_ {g} dot {a} (t))$$ it is a vector field dependent on time. Therefore, maybe the first previous equality is not valid? How is one interpreted then? $$(T_ {a (t)} L_ {a ^ {- 1} (t)} point {a} (t)) f$$?

## What are the most used and basic Apache htaccess redirects?

### Mod_alias and Mod_rewrite

There are 2 modules that you can use inside the htaccess to control the redirects that are known as mod_alias and mod_rewrite. To help you establish the difference between the following two, there are some commands to become familiar when you are using mod_alias or mod_rewrite.

mod_alias commands

mod_rewrite commands

mod_alias is considered a simpler redirect method, while mod_rewrite is considered more advanced and allows more directives. It is worth noting that the mod_rewrite commands are executed before mod_alias.

### Redirection codes

• 301 Permanent
• 302 Temporary

### How to redirect an old URL to a new URL?

There are many ways to redirect a page to another using htaccess, 301 is generally the most important and the most used, since most pages will need permanent and not temporary redirects. The permanent redirects are excellent to try to keep the classifications from one page to another.

301 permanent

Redirect 301: `Redirect 301 /old.html http://www.example.com/new-url/`

RedirectPermanent: `RedirectPerm /old.html http://www.example.com/new-url/`

RedirectMatch: `RedirectMatch 301 ^ old.html \$ http://www.example.com/new-url/`

RewriteRule:

``````RewriteEngine On
RewriteBase /
RewriteRule ^ old.html \$ http://www.example.com/new-url/ [R=301,NC,L]
``````

302 Temporary

Redirect 302: `Redirect 302 /old.html http://www.example.com/new-url/`

RedirectTemp: `RedirectTemp /old.html http://www.example.com/new-url/`

RedirectMatch: `RedirectMatch 302 ^ old.html \$ http://www.example.com/new-url/`

RewriteRule:

``````RewriteEngine On
RewriteBase /
RewriteRule ^ old.html \$ http://www.example.com/new-url/ [R,NC,L]
``````

### Capture everything and redirect not www to www

You must choose to use mod_write to redirect all requests for non-www versions of your site because the \$ 1 variable will detect the names of the pages, so that `example.com/page1/` it will be redirected automatically to `www.example.com/page1/`.

mod_rewrite:

``````RewriteEngine On
RewriteCond% {HTTP_HOST}! ^ Www .
RewriteRule ^ (. *) \$ Http: //www.% {HTTP_HOST} / \$ 1 [R=301,L]
``````

mod_alias:

``````

Permanent redirect / http://www.example.com/

``````

### Capture everything and redirect www to no-www

mod_rewrite:

``````RewriteEngine On
RewriteCond% {HTTP_HOST} ^ www.example.com \$ [NC]
RewriteRule ^ (. *) \$ Http: //example.com\$1 [R=301,L]
``````

mod_alias:

``````

Permanent redirect / http://example.com/

``````

### Capture everything and redirect www to no-www (HTTPS)

``````RewriteEngine On
RewriteCond% {HTTP_HOST} ^ www.example.com \$ [NC]
RewriteRule ^ (. *) \$ Https: //example.com\$1 [R=301,L]
``````

### Enforce TLS on specific pages and disable at rest

This script will delete TLS on all other pages, apart from the login page and the registration page, you can add more only use `|` as the separator between file names.

mod_rewrite:

``````RewriteCond% {HTTPS} on
RewriteCond% {SCRIPT_FILENAME}!  / (Login | register) . Php [NC]
RewriteRule ^ (. *) \$ Http: //% {HTTP_HOST} / \$ 1 [R=301,L]
``````

### Enforce TLS throughout the site

If you want to apply TLS to the entire site, you can use mod_rewrite to detect that HTTPS is disabled.

mod_rewrite:

``````RewriteEngine On
RewriteCond% {HTTPS} disabled
RewriteRule (. *) Https: //% {HTTP_HOST}% {REQUEST_URI}
``````

### Removing URL extensions using mod_rewrite

Some web servers may require `Options -MultiViews` In your htaccess to eliminate these extensions, try it without it and, if it does not work, simply add it.

Removing the PHP extension type:

``````RewriteEngine On
RewriteCond% {REQUEST_FILENAME}! -F
RewriteRule ^ ([^.]+) \$ \$ 1.php [NC,L]
``````

Deleting the HTML extension type:

``````RewriteEngine On
RewriteCond% {REQUEST_FILENAME}! -F
RewriteRule ^ ([^.]+) \$ \$ 1.html [NC,L]
``````

Removing the HTM extension type:

``````RewriteEngine On
RewriteCond% {REQUEST_FILENAME}! -F
RewriteRule ^ ([^.]+) \$ \$ 1.htm [NC,L]
``````

It does not work? Try this (change php to the file extension you want to delete):

``````Options -MultiViews
RewriteEngine On
RewriteCond% {REQUEST_FILENAME}! -D
RewriteCond% {REQUEST_FILENAME}! -F
RewriteRule ^ ([^.]+) \$ \$ 1.php [NC,L]
``````

### Extraction and application of inclined bars

Fulfillment:

This will redirect all requests without a trace `/` to the URL with the bar at the end. (the note inside the second part of the bracket are the file extensions that should be ignored … since it would not make sense to apply them `/` in an image URL.

``````RewriteCond% {REQUEST_URI}!  (Php | html? | Jpg | gif) \$
RewriteRule ^ (. *) ([^/]) \$ http: //% {HTTP_HOST} / \$ 1 \$ 2 / [L,R=301]
``````

Removing:

``````RewriteEngine On
RewriteCond% {REQUEST_FILENAME}! -F
RewriteCond% {REQUEST_URI} (. *) \$
RewriteRule ^ (. +) / \$ Http://www.example.com/\$1[R = 301, L
``````

### Convert bars to bars forward

This will convert all the backslashes found in a URL to slashes. Good to prevent duplicate content:

``````RewriteEngine On
RewriteCond% {REQUEST_URI} (. *) \ (. *)
RewriteRule. *% 1 /% 2 [R=301]
``````

### Redirect the old domain to a new domain

``````RewriteEngine On

# Redirect the entire site to a new domain
RewriteCond% {HTTP_HOST} ^ example.com \$ [OR]
RewriteCond% {HTTP_HOST} ^ subdomain.example.com \$ [NC]
RewriteRule ^ (. *) \$ Http://new-example.com/\$1 [R=301,L]
``````

### Redirect to new domain and delete subfolder

``````RewriteEngine On

# Rename folder to match the subfolder you want to delete
RewriteCond% {HTTP_HOST} ^ (www .)? Example-old  .com \$ [NC]
RewriteRule ^ folder (/.*)? \$ Http: //www.example-new.com\$1 [L,R=301]
``````

## Static MPLS basic configuration for Cisco 3725 in GNS3

I need to forward an MPLS packet from Router 1 to Router 2 (as shown in the following Scenario figure). The connection summary is:
Cloud-1 <--> R1 <--> R2 <--> Cloud-2 I have tried the basic static configuration for the R1 interfaces and the static label tags link as well. I've also added routes for R1 (I'm testing R1 just to see if it's capable of forwarding it to R2). Cloud-1 and 2 are virtual interfaces to a hardware device installed on the same server that GNS3 is running. It will send and receive packets labeled MPLS and I have verified that it works (that is, it forwards MPLS packets to R1) and I can capture packets between Cloud-1 and R1 and see the packet sent from Cloud-1 to R2. These virtual interfaces work as PE routers, since the packages will be tagged from them.

Script

This is the configuration for R1:

``````enable
configure terminal
mpls ip
FastEthernet0 / 1 interface
mpls ip
not turn off
finish
configure terminal
mpls ip
FastEthernet0 / 0 interface
mpls ip
not turn off
finish
configure terminal
label range mpls 10001 1048575 static 16 10000
mpls static link ipv4 10.0.1.0 255.255.255.0 2222
mpls static link ipv4 10.0.2.0 255.255.255.0 1001
mpls static link ipv4 10.0.1.0 255.255.255.0 output 192.168.0.1 3333
mpls static link ipv4 10.0.2.0 255.255.255.0 output 192.168.1.2 2002
ip route 10.0.1.0 255.255.255.0 FastEthernet0 / 0
ip route 10.0.2.0 255.255.255.0 FastEthernet0 / 1
finish
``````

The packet that R1 will get from Cloud-1 has 10.0.1.1 as src IP and 10.0.2.1 (a host that will be in cloud 2). The MPLS tag is 1001 in that package.

I do not see any packet forwarded to R2.

This is the output of some of the relevant commands. Note that there is no entry in LFIB and I am not sure why, as most manuals on Cisco sites and tutorials suggest that there should be an entry in the MPLS forwarding table with respect to static links what I did

``````R1 # show mpls label range
Descending generic label region: Min. / Max: 10001/1048575
Range for static labels: Minimum / maximum number: 16/10000
R1 # show mpls static link ipv4
10.0.1.0/24: Incoming label: 2222
Outgoing tags:
192.168.0.1 3333
10.0.2.0/24: Incoming label: 1001
Outgoing tags:
192.168.1.2 2002
R1 # show mpls forwarding-table
Byte tag of local output prefix Jump next hop
tag tag or VC or tunnel identification switching interface
R1 #
``````

The packet sent to R1 looks like this (the destination MAC address is, in fact, the Fa0 / 0 MAC of R1 in case it could be a reason to remove packets, I suppose):

``````###[ Ethernet ]###
dst = c2: 02: 72: 6b: 00: 00
src = da: a5: a2: dd: 5c: 8b
type = 0x8847
###[ MPLS ]###
label = 1001L
exp = 0L
bos = 1L
ttl = 254
###[ IP ]###
version = 4L
ihl = 5L
tos = 0x0
len = 20
id = 1
flags =
frag = 0L
ttl = 64
proto = hopopt
chksum = 0x63e8
src = 10.0.1.1
dst = 10.0.2.1
options
``````

Any help is appreciated.

## 8 – Add a block of view at a basic rhythm with Acquia

I have been assigned the task of creating a new basic page that contains the content of some new content. So far, I created the basic page, and I also created a new block of view (that is, I went to structure-> views and added a new block).

Now I need to show this block of view on the basic page that I created. From my (small) understanding of Drupal, I think I need to add a line like this:

``````

``````

to the template file of my basic page located at `sites / all / themes / mytemplates / node - 12516.tpl.php`.

However, this project is hosted in Acquia and I'm not sure how to download that file to edit it (if it exists).

How can I tear down these types of changes with Acquia? Or am I going to do all this wrong? How am I supposed to add a block of view to a basic page?
