Re: [users@httpd] Re: Reg : Limiting http connections at Apache 2.4.25
You should not "compile in" any MPM, compile them all as modules and
load one in configuration. That just reveals you probably didn't use
"--enable-mpms-shared"
As per configure script help:
--with-mpm=MPM Choose the process model for Apache to use by
default. MPM={event|worker|prefork|winnt} This will
be statically linked as the only available MPM
unless --enable-mpms-shared is also specified.
Try again with something like:
--enable-mpms-shared=all --with-mpm=event
Issue a "make clean" first if necessary.

Thanks Luca, your help is much appreciated.
I was able to compile and load mod_qos in Apache 2.4.25 proxy.
There are many parameters related to QOS, I am trying to implement a
parameter to restrict HTTP session beyond specified limit, example I would
like to allow only maximum 100 connections, beyond that should throw an
error.

Vel

Re: [users@httpd] Re: Reg : Limiting http connections at Apache 2.4.25
Hi, sorry to trouble again. I used "QS_SrvMaxConn" parameter in mod_qos to restrict sessions, it does restriction but based on HTTP TCP connection based, but I would like to restrict session based. Apache has to count the persistent connection with back-end server and then restrict further connections. is this feasible to consider the persistent connection after authentication done by webblogic, may be through cookie?

Re: [users@httpd] Re: Reg : Limiting http connections at Apache 2.4.25
Hi, I think that you'd just need to install httpd without any reference to mod_qos (that is a third party module, so configure is not aware of it) and finally use apxs to compile/install the new module (more info in https://httpd.apache.org/docs/2.4/programs/apxs.html). I'd also suggest to test it with httpd 2.4.25 rather than 2.2.27 :) Hope that helps!

Indeed, but I don't think that's what the OP is looking for in an apache proxy. Rather the proxy reply with a "too busy" error page than not take the connection at all, right? The proxy balancer would be a place to look: that offers various ways to determine how much traffic to send to a backend. If that doesn't meet your needs, there are several third-party traffic- limiting modules. -- Nick Kew - To unsubscribe, e-mail: users-unsubscr...@httpd.apache.org For additional commands, e-mail: users-h...@httpd.apache.org >

Not sure what is the status of mod_qos (third party module), but you might want to give it a try and see if it fits your needs! http://mod-qos.sourceforge.net/#requestlevelcontrol Luca 2017-04-17 3:08 GMT+02:00 Velmurugan Dhakshnamoorthy : > Dear All, > Any specific setup to cut and disallow the the further HTTP connections > after specified limit (ex: 50 sessions?). > > My requirement is to allow only 50 users and 51st user should get a custom > error message to login after sometime. > > Regards, > Vel > > On Mar 16, 2017 21:30, "Velmurugan Dhakshnamoorthy" > wrote: > >> Thanks for response, >> >> Yes my requirement is to completely restrict/disalllow any further >> connections, example I want to allow only 50 sessions, 51st connection >> should get an error message to login later after certain period of time. >> >> >> Regards, >> Vel >> >> On Mar 16, 2017 18:58, "Nick Kew" wrote: >> >>> On Thu, 2017-03-16 at 02:05 +0100, Daniel wrote: >>> > See about mpm settings/directives such as MaxRequestWorkers, which >>> > will limit the number of concurrent requests your server can take. >>> >>> Indeed, but I don't think that's what the OP is looking for in an >>> apache proxy.

Re: [users@httpd] Re: Reg : Limiting http connections at Apache 2.4.25
Dear All, Any specific setup to cut and disallow the the further HTTP connections after specified limit (ex: 50 sessions?). My requirement is to allow only 50 users and 51st user should get a custom error message to login after sometime.

Re: [users@httpd] Re: Reg : Limiting http connections at Apache 2.4.25
Thanks for response, Yes my requirement is to completely restrict/disalllow any further connections, example I want to allow only 50 sessions, 51st connection should get an error message to login later after certain period of time.

Re: [users@httpd] Re: Reg : Limiting http connections at Apache 2.4.25
See about mpm settings/directives such as MaxRequestWorkers, which will limit the number of concurrent requests your server can take. Note this is not an exact science you need to test your mpm settings to suit your own needs. 2017-03-16 1:08 GMT+01:00 Velmurugan Dhakshnamoorthy : > Dear All, > Any help on my earlier post regarding throttling HTTP connections. > > Regards, > Vel > > On Mar 14, 2017 21:27, "Velmurugan Dhakshnamoorthy" > wrote: > >> Hi Everyone, >> >> I just joined to this group. >> >> I have installed Apache 2.4.25 HTTP server as a reverse proxy server and >> my back-end content server is Weblogic 12c(12.1.3). >> >> I would like to limit/restrict HTTP connections at Apache layer (example >> : only maximum 50 HTTP sessions to be allowed) .What is the configuration >> required to achieve this restriction. >> >> My OS is RHEL 7.2, your help and support on this matter is highly >> appreciated. >> >> Regards, >> Vel >> > -- *Daniel Ferradal* IT Specialist email dferradal at gmail.com linkedin es.linkedin.com/in/danielferradal

Dear All, Any help on my earlier post regarding throttling HTTP connections.
