RewriteRule not working - .htaccess

This is the contents of my .htaccess file:
RewriteEngine on
RewriteRule ^upload$ upload.php
RewriteRule ^/(\d+)/?.*$ /view.php?id=$1 [L]
The first rule successfully works. When I navigate to http://localhost/upload it shows the upload.php page.
The second rule however, does not. When I browse to: http://localhost/1234/some-string I get a 404 error. It's meant to show this page: http://localhost/view.php?id=1234.
Hopefully you can see what I'm trying to do with the rule, I want the last string on the end of the URL to be completely ignored, and take the 1234 as a parameter for view.php.
Can anyone spot why this isn't working? I've tried everything I can think of, but to no success. Thanks!

it will be trying to find the directory /1234/ and failing. change the / to a - and it should work
EDIT: got that completely wrong ... it's actually that you have a / at the beginning of your pattern, whereas MOD_REWRITE receives the path without the first slash.

I am not able 301 redirect domain.tld/?cur=usd to domain.tld

I try to redirect domain.tld/?cur=usd to domain.tld (there are many curencies, this is only example of one currency - we do not use anymore this solution).
I need to redirect only home with parameter to home without parameter. The other urls worked for me, I'm just having trouble getting work with that one.
I try to search and use online generators but none of the solutions work.
Here is what I am trying:
RewriteCond %{QUERY_STRING} (^|&)cur\=(.*)($|&)
RewriteRule ^$ /? [L,R=301]
// update
before this rule I have only
#bof redirects
RewriteEngine enabled
...and then there are redirects for other URLs, but I tested this rule separately first and the result was the same...
It not redirect me.
Thanks for the help and maybe an explanation of what I'm doing wrong.
RewriteCond %{QUERY_STRING} (^|&)cur\=(.*)($|&)
RewriteRule ^$ /? [L,R=301]
As mentioned in comments, this should already do as you require, providing there are no conflicts with other directives in the .htaccess file.
However, the regex in the preceding condition is excessively verbose for what you are trying to achieve (ie. just testing for the presence of the cur URL parameter).
If you simply want to check for the cur URL parameter anywhere in the query string then the regex (^|&)cur= would suffice (and is more efficient). No need to backslash-escape the literal =. And if the URL parameter always appears at the start of the query string then just use ^cur=.
I found the problem - it was something with the hosting, after a reboot everything started working as expected.
So I can confirm that this rule is fine.
Sorry for question.

Redirects not working as expected

I have an .htaccess file with several lines. It does not work as expected. Mod_rewrite is enabled. RewriteLogLevel is set to 9.
The first two rules are there to forbid uris with a length more then 80 characters:
RewriteCond %{REQUEST_URI} ^.{80}
RewriteRule .* - [F]
It does not seem to get evaluated as every test url passes through and it does not generate an error either.
I also tried:
RewriteRule .{80} - [F]
But that did not do the trick either. The process ends with a 404, not a 403.
This next rule is not working either. It used to work.
RewriteRule ^(\/)?([\w]+)$ /index.php [L]
The URI /Contact was always handled by this index.php.
Whatever URL I type I get a 404. I should get a 403 or a 200. Not a 404. What am I missing?
Apache has on all directories the permission to read, write and execute and on all files the permission to read and write.
The two urls for testing are:
127.0.0.4/asssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssddddddddddddddddddddd?p=s&s=psv
and
127.0.0.4/Contact
The alias for 127.0.0.4 used is considerate.lb.
Try this rule instead:
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s/+\S{80}
RewriteRule ^ - [F]
Using THE_REQUEST instead of REQUEST_URI as that variable might get overwritten due to presence of other rules in your .htaccess
Finally I have found a solution. The problem was not in the coding of the .htaccess. I replaced the file with a previous version, added the new lines to test the request and it worked all fine.
It is not a satisfactory solution, because it can happen again and I do not have any clue what caused the error. If someone knows the error, I would love to hear what might have been the exact cause and how to solve that properly. I would like to change the tags of the question as the current tags might be misleading (although other people might experience the same problem how apache handles a .htaccess file), but I do not know which tags I should use.

Htacces rewrite rules and conditions

I have this rule which works perfectly
RewriteEngine on
RewriteRule ^([^/]+)/([^/]+) /demo/index.php?category=$1&subcategory=$2
this converts my link from
/demo/index.php?category=ABC&subcategory=XYZ
to
/demo/ABC/XYZ
but at times I want to enter just the category name like this
/demo/ABC/
But unfortunately this gives error Page not found. What causes this error and how can I fix it?
Also can someone provide link to RewriteEngine resources/books/tutorials. I couldn't find anything that would help a beginner like me. Thank you.
Change your rule to:
RewriteRule ^([^/]+)/([^/]*) /demo/index.php?category=$1&subcategory=$2 [L,QSA]
This making second argument optional (using * instead of + in [^/]*)
Unless /demo/ABC/ is a directory that exists on your local file system, it won't be able to find the page. Your first rule is only rewriting that parameter-filled link into that pseduo-path, it doesn't establish a virtual directory or create a solid redirect.
The best info for RewriteRule is probably going to be in the actual Apache docs.

using mod_rewrite to strip out junk

We're seeing some really weird URLs in our logs and I've been told to start redirecting them.
I know of a couple of better ways to go about fixing this, but the boss wants it done this way. I apologize in advance.
We're seeing stuff like the following in our logs:
http://www.example.com/foo/bar/bla&ob=&ppg=&rpp=100&ob=&rpp=&ppg=&rpp=30&ppg=&ppg=1&rpp=10&rpp=50&ob=&ob=&ob=&rpp=40&ob=&rpp=5&rpp=30&rpp=&rpp=20&order_by=&results_per_pge=75
I've been told to 'toss some mod_rewrite rules in the .htaccess file' to take this and strip out all the ob, rpp, and ppg variables.
Now, I've found ways to strip everything out. And that wouldn't be too bad if I could leave the /foo/bar/bla in there. But I can't seem to do that. Basically, any help would be appreciated.
Try:
# strip out any params that's ob=, rpp= or ppg=
RewriteRule ^/?(.*)&ob=([^&]*)&(.*)$ /$1&$3 [L]
RewriteRule ^/?(.*)&rpp=([^&]*)&(.*)$ /$1&$3 [L]
RewriteRule ^/?(.*)&ppg=([^&]*)&(.*)$ /$1&$3 [L]
# if everything's gone, finally redirect and fix query string
RewriteCond %{REQUEST_URI} !&(ob|rpp|ppg)
RewriteRule ^/?(.*?)&(.*) /$1?$2 [L,R=301]
The problem here is that your URL:
http://www.example.com/foo/bar/bla&ob=&ppg=&rpp=100&ob=&rpp=&ppg=&rpp=30&ppg=&ppg=1&rpp=10&rpp=50&ob=&ob=&ob=&rpp=40&ob=&rpp=5&rpp=30&rpp=&rpp=20&order_by=&results_per_pge=75
has A LOT of ob=, rpp=, and ppg= in the URI. More than 10. That means you'll get a 500 internal server error if you use these rules against that URL. By default, apache has the internal recursion limit set to 10, that means if it needs to loop more than 10 times (and it will for the above URL), it'll bail and return a 500. You need to set that higher:
LimitInternalRecursion 30
or some other sane number. Unfortunately, you can't use that directive in an htaccess file, you'll need to go into server or vhost config and set it.

rewriteRule for URL path not working correctly

I need help with a URL problem I've encountered with a rewriteRule.
What I need it to do is following: example.com/en/page/page/
At the moment the following works fine: example.com/en/page/
But once it goes like "example.com/en/page/page/" I receive a 404 - page not found error even if the page in fact is located in the serverfiles.
The clue here is that I use a variable in the /en/ part of the URL (multilanguage system) and it seems that I cannot figure out how to get it to work with that included.
At the moment I have the following rewriteRule in my .htaccess file.
RewriteRule ^([^/]*)/([^/]*)/?$ index.php?lang=$1&uri=$2 [L]
Do any of you have a clue on what might work?
Best regards,
PureDarkness
You don't include anything behind the second /. You could try:
RewriteRule ^([^/]*)/(.*)$ index.php?lang=$1&uri=$2 [L]
And you can add [QSA] if you also need to get the parameters.
