Apache :: Perform SSO To Application - How To Increase HTTP Header Size
Dec 5, 2014
I'm trying to perform SSO to my application. for my login i get an error "Size of a request header field exceeds server limit". I believe the header size got increased then the limit set in apache server. I'm guessing so.
the flow of request: Apache -> tomcat -> SAP Business Objects.
For my colleagues login the SSO works fine with out issue.
So, how to increase the HTTP header size. I'm bridging apache and tomcat using AJP connector. below is the AJP connector parameters in server.xml
I have a virtual server with CentOS 6.4 (Final) and Plesk 11.5.30 and I would like to increase the database size to import because right now it's only 2MB and I have to put online a website with 10MB.
I'm running Plesk 12. I install it today, using the ISO which parallels provides, which includes centos 6.5 and preinstalled Plesk 12 in my vps. Then I logged in plesk, and I did everything it wants. Then I upgraded my php, to php 5.4.36 according to the manual that Paralells provides, and then I tried to increase the max upload file size for phpmyadmin. I have edited my /usr/local/psa/admin/conf/php.ini file and tried to restart using with 3 different ways using terminal:
1st: service sw-cp-server restart 2st: /etc/init.d/psa stop /etc/init.d/psa start 3st: reboot (which rebooted all the vps)
My php.ini file is:
short_open_tag = On y2k_compliance = Off output_buffering = Off max_execution_time = 600 max_input_time = 600 memory_limit = 256M max_file_uploads = 99999 max_input_vars = 2000
[Code] ....
However, when I'm trying to import a 31mb sql file, I always get that error, and only some of my tables are being imported:
#1153 - Got a packet bigger than 'max_allowed_packet' bytes
I am using 2.2.29 in Windows.Trying to remove one cookie in a request header before passing the request to the application, but having trouble. The cookie is in the middle of the request header.
I'm looking for a way to add a script in the header tag of a web page without using a CMS or anything like that.it should be the first script that is running when the page is rendered.I'm running Apache 2.2.25 and Tomcat 7.0.50 - both Win32 versions.
There are two reasons for an approach like that.
(1) - I expect it to work regardless the CMS I'm working with; the same expectation is for Tomcat and Java applications. (2) - I'm able to start this as early as possible => includes monitoring the performance of the CMS itself.
My configuration is Apache 2.2.3 using Tomcat - AJP with mod_proxy_ajp, mod_ssl.We have configured Kerberos but some users are getting an error - Size of a request header field exceeds server limit.
Users with headers above 8K are getting this error, users less than 8K can get in fine. How can I increase this header limit in Apache/Tomcat? I have tried multiple suggestions found on google and other sites.
Here is what I tried:
Adding the following to the http.conf LimitRequestFieldSize 65536 ProxyIOBufferSize 65536
Adding the following to server.xml packetSize="65536"
editing a workers.propeties file, but we dont have any files on the server with that name.
How to increase the Open Files limits descriptor in Apache. In the earlier version of Cpanel, we had an option of Raise FD Size Limit to 16384, but the option no longer appear while rebuilding Apache. What is the way to do it and make the change permanent?
On our production service, we've been getting numerous malformed POST requests to some of our CGI scripts that are showing up as 500 errors in our logs. They are malformed in the sense that the actual content length doesn't match the Content-Length specified in the request.
Here's the most trivial example I can come up with that reproduces the problem for us:
In addition to the 500 error in the access log, we see the corresponding error in the error log:
(70014)End of file found: Error reading request entity data
Based on the nature of the POST request and the error response, it does appear that Apache is doing the right thing here.
The POST never actually makes it as far as the script being targeted (/some_valid_alias in the above example); in other words, Apache returns 500 to the client, writes the error to the error log and never executes the script.
Is there a way to capture/avoid internal Apache errors like 70014, and return some other HTTP status besides 500 (like 403)? It's particularly annoying in our case, because our server sends us an email for all 500 errors.
So far, our best "defense" against these 500 errors is to disallow POST for these aliases, which normally just ignore the POST data anyway (when the request is not malformed):
I have a 2,3 and 5GB files that I need to download but everytime they appear as 1.4GB for some reason. I've tried IE, Mozilla and opera and the same result each time.
Is there some sort of limit to the size of a file that apache will serve?

I'm trying to integrate the websocket into existing application.Based on my search, i found a websocket module to do this, but it isn't updated yet. URL...
Any chance that the module will be included in Apache ? Also i found in StackOverflow conversation that Apache httpd wasn't design to maintain persistent connection, is that true ? Using WebSocket on Apache server. Should continue using Apache websocket module or using separate websocket server ?
I have Apache 2.2 installed on Windows to host a web2py application using wsgi.
Apache crashed once stating it had run out of worker threads, so I inscreased ThreadsPerChild to 500. It has since crashed/become unresponsive without giving anything in the error log.
I set up mod_status, and am looking for understanding what I see when looking at server-status page.
It says 135 requests currently being processed, 365 idle worker. However I don't think there are 135 people connected.
Here's the request lines:
SrvPIDAccMSSReqConnChildSlotClientVHostRequest 0-1253840/0/0W138495448300.00.000.00 ... the line above is repeated identically 125 times 0-1253840/32/32W000.00.460.46127.0.0.1dalgety-svr8.havelock.intGET /server-status HTTP/1.1 0-1253840/0/0W52400.00.000.00192.168.202.109dalgety-svr8.havelock.intGET /HubForms/ProjectFolderIndexing/index HTTP/1.1
[Code] ....
Question:
1) What are those 125 requests, and why are they not exiting. Are they anything to worry about? why is there no Client/VHost/Request? Could they be from the python process? Could they be what's causing the issue?
2) The Acc entry 0/121/121 on /HubForms/capacity_requests/index - is this representative of an issue?
3) When I restart Apache, it typically says "Terminating 375 threads that failed to exit" but that number doesn't match up with anything. Are these the idle threads?
Also I'm not sure what "restart" actually means, i.e. what stops and what stays (i.e. why am I on generation 0-12?).
4) Is any of this anything to do with why Apache becomes unresponsive, or should I be looking elsewhere?
One of our resellers has an account.. When looking into cpanel, it says that that account is using 3300megs. When we go into the ftp of that account, in reality it is only using 1.3megs. This is a huge difference! Most of folders are empty. We are using the latest version of WHM and Cpanel.
