Yahoo Slurp China htaccess block

Slurp China htaccess block

[cyberdyne]

Hi,
A little advice please.
Would the following block Slurp as well as Slurp China? I don't want to block Slurp (US).

RewriteCond %{HTTP_USER_AGENT} ^Slurp\ China [NC,OR]

Thank you.

I'm not sure of the UA, as I haven't seen it.

I've had the 202 range that they crawl from denied since they began crawling from it.

Have the following in robots.txt

User-agent: Yahoo! Slurp China
Disallow: /

Thanks wilderness.

The log read:

T /robots.txt HTTP/1.0" 302 419 "-" "Mozilla/5.0 (compatible; Yahoo! Slurp China; http://misc.yahoo.com.cn/help.html)"

I get hit by Yahoo! Slurp China quite a bit and would like to block it while permitting Slurp (US).

Thanks

You may also use the following:

RewriteCond %{HTTP_USER_AGENT} "Slurp China" [NC,OR]

without using the escapes.
The use of quotes results in "exactly as".

Absence of the leading ^ (starts with) catches the term anywhere in the UA.

Great, I'll use that.
Thank you Don

cyberdyne, if using mod_rewrite you'll need to escape the space as you did in your first post, but leave off the starting anchor:

RewriteCond %{HTTP_USER_AGENT} "Slurp\ China" [NC,OR]

Actually, you could just block anything with "China" in the UA:

RewriteCond %{HTTP_USER_AGENT} "China" [OR]

[cyberdyne]

OK keyplyr, I'll amend it :)
Thank you.

Hey keyplr,
that's not correct!
Use of quotes utilizes "exatly as" and includes spaces (or any other character) without requiring escaping of the
space.

Additionally, when using the simgle word China, adding quotes is redundant.

As an aside, you may recall another who came into this forum some time ago and was utilizing quotes on every line because that was the example both provided and expressed in Apache?
It's simply not requried on every line.

Wilderness, can you confirm that the original:

RewriteCond %{HTTP_USER_AGENT} "Slurp\ China" [NC,OR]

is indeed correct?

Thank you :)

[wilderness]

cyberdyne,
That will work.

The escape however is redundant and not necessary due to use of quotes. (the escape is necessary without the use of quotes)

Your original inquiry included the leading ^ which would not function because the UA does not begin with those terms.

Please don't be confused by this?
It's merely a matter of clarification of practices which help to provide insight into more complicated reg ex. As well as consistency in the usage of pattern for our personal clarification (a solitary error in syntax may and will result in both your htaccess and website (s) from functioning)

RewriteCond %{HTTP_USER_AGENT} "Slurp\ China" [NC,OR]
OR
RewriteCond %{HTTP_USER_AGENT} "Slurp China" [NC,OR]
OR
RewriteCond %{HTTP_USER_AGENT} Slurp\ China [NC,OR]
OR
RewriteCond %{HTTP_USER_AGENT} China [NC,OR]

All three (four; edited to add lone China) above accomplish the same desired effect.
However, I would caution you against not chosing a particular method and then conforming to that method in your practicses.
The result of inconsistency in reg ex amy result in you spending days to determine a syntax error (should you htaccess ever grow large).

keyplr is far more adapt at writing extensive expressions than myself, however I've benefitted from "KISS" in my use of htaccess.

Don, it was very late when I posted. I just cut'n pasted the example without even noticing those quotes - duh. Ever since I started running dual monitors juggling multiple windows, I'll notice more mistakes as the night grows long.

Thanks for correcting me. I hate it when misinformation is posted as valid.

keyplr,
I've a hard enough time keeping track of what comes across one...do the dual monitors affect your ability to focus?

There are occassional days when my eyes or simply out of focus and I'm not able to function with a computer screen.
