[users@httpd] httxt2dbm - DB file not completely rewritten
I use DBM rewrite maps (apache 2.2.9 - package 2.2.9-10+lenny6) on debian 5
with BerkeleyDB 4.6 (package 4.6.21-11). I generate the DB files with
makefiles that call httxt2dbm on potentially already existing DB files.
When entries are added to the source files, it works fine. But when entries
are deleted from the source files, the DB files still contain the entries and
lookup succeeds (and yes, I verified that the DB file is indeed updated).I
also grepped the db file for the key to verify that it is indeed in the file
(and not a cached result in apache).
Is this a bug in httxt2dbm, or is my expectation wrong? Thanks for any
comments!
Rainer

Finally, I found that an issue was raised :
Bug 51372 httxt2dbm does not remove map entries
<https://bz.apache.org/bugzilla/show_bug.cgi?id=51372>
It was solved by a documentation update in Apache trunk.
As a matter of fact, the Apache 2.4 documentation says :
If the output file already exists, it will not be truncated. New keys will
> be added and existing keys will be updated.
Apache 2.2 documentation was not updated yet.

Hi Rainer,
I have the same issue ... 5 years later ;) with Apache 2.2.22, and even
with Apache 2.4.10.
Did you get an explanation (or I will raise an issue).
Thanks
Antoine.

I know its possible. A particular service I use (a private one) will
only handle so many requests, then simply return an "I cant do that,
DAV" 401 [svc unavailable]

You can't.
Well, you could write a module for it. If you can live with ballpark
numbers, I'd suggest limiting the number of threads per process
on a restricted task, rather than maintaining a global count.
Or if this is about system load, consider something like
mod_load_average.

I don't know bout limiting no. of requests, but using <Limit> and
LimitRequestBody, you can control the maximum size of uploads / downloads.

[users@httpd] How to limit number of particular request in apache.
Posted by Anuradha <ds...@yahoo.co.in>.
Hi All,
I want to limit the number of "particular" requests in apache
For example
I have httpd running on my system. My webserver provides a upload and download service.
I want to configure appache in a way that at the max it can serve 100 uploads and 200 downloads not more than that.
When I looked into the archives I came across MaxConnPerIP where they are limiting request per IP
Wondering if there is any configurable parameter to limit on particular request.
Thanks,
Anu.
