How to block bad-bots in htaccess - .htaccess

I've used htaccess to block bad bots. I found a complete list of them which are around 400 items and put a code like below in my .htaccess file, but I got 500 Internal Error on my web server.
<IfModule mod_setenvif.c>
SetEnvIfNoCase User-Agent ^$ bad_bot
SetEnvIfNoCase User-Agent "^WebReaper [webreaper#otway.com]" bad_bot
SetEnvIfNoCase User-Agent "^WebZIP/5.0 PR1 (http://www.spidersoft.com)" bad_bot
SetEnvIfNoCase User-Agent "^Wget/1.8.1+cvs" bad_bot
SetEnvIfNoCase User-Agent "^Zeus 97371 Webster Pro V2.9 Win32" bad_bot
<Limit GET POST HEAD>
Order Allow,Deny
Allow from all
Deny from env=bad_bot
</Limit>
</IfModule>
I also found that it's not about the size of data, but the codes seems to have a problem. How can I fix this problem?

Below is a useful code block you can insert into.htaccess file for blocking a lot of the known bad bots and site rippers currently out there

htaccess ReWriteRule giving 500 error rather than 403

In my htaccess file I am blocking site access by referer, remote host and user agent but the following list is returning 500 errors rather than 403's.

What's the right way to disallow crawlers by .htaccess?

I've got my company (internal use) website indexed by Google when I've added such rule in the .htaccess:
RewriteBase /
RewriteCond %{HTTPS} off
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
robots.txt appear to be right by having one rule:
User-agent: *
Disallow: /

Fixing an htaccess 404 not found issue

I'm trying to figure out why I'm getting a 404 Not Found issue.
The requested URL /welcome was not found on this server.
I am running on a localserver with Mamp Pro. I set up a new server on port 80 with dev.mysite.com and have it pointed to the correct file path for the document root.
Is there any settings within the server on Mamp Pro I need to set up for that server.
- Sites
- mysite
- application
- controllers
welcome.php
- public_html (document root)
index.php
- assets
- system
When I load the welcome controller with the following link I get the welcome controller successfully.
dev.mysite.com/index.php/welcome
When I go to the following link I get a 404 Not Found error because it can't the requested URL on the server.
Here is what I'm using for a .htaccess file.
RewriteEngine on
#remove index from url
#RewriteCond $1 !^(index\.php|assets)
#RewriteRule ^(.*)$ /index.php/$1 [L]
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ /index.php/$1 [L]
# Removes trailing slashes (prevents SEO duplicate content issues

What's wrong with my htaccess please - it causes an occasional loop

I think my htaccess is a bit of a mess....
It is causing a very odd problem, that is, that if you hit my blog (which is in a subdirectory and where this htaccess resides) - and then you hit another link to leave the blog subdirectory - the site sometimes throws a loop error...
Thanks for all help with this - you'll really be helping!

I doubt it's being caused by your htaccess file. Everything all the way down to the wordpress rules just denies access (and some are commented out). Then you have your wordpress rules:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /security/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /security/index.php [L]
</IfModule>
# END WordPress
And as long as the htaccess file is in the /security/ folder, they look fine.

Block "internet download manager" on music stream site with .htaccess?

I have a site where people listen to music and I have blocked some software that lets users download (I use .htaccess). Now I have encountered these pieces of software:
Internet Download Manager
Free Download Manager
Download Accelerator Plus
Please let me know how can I block these?
thanks
Blocking by user agent is not a good way to go since every decent download manager will send the request with a browser's user-agent header.
For example, IDM 6.06 (current version) send the following user agent for chrome:
Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/534.24 (KHTML, like Gecko) Chrome/11.0.696.57 Safari/534.24
Then again for IE it uses:
Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C; .NET4.0E; InfoPath.3)
Guess what IE sends without IDM:
Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C; .NET4.0E; InfoPath.3)
Reason is that IDM captures information using a network driver, so basically it 'steals' the request from your web browser and sends the exact information it sends.
This code must be help to prevent bad bots , IDM and most of the download manager. Add this to your server htaccess

Essentially it should be something like this. Google for "Blocking by user agents htaccess".
Options +FollowSymlinks
RewriteEngine On
RewriteCond %{HTTP_USER_AGENT} "Download Accelerator Plus"
RewriteRule ^(.*)$ http://mypage.org/error.html [R=301,L]
See the Apache Docs on mod_rewrite for more complex conditions.
