  • Webmin apache on CentOS 6.3 results in 403 forbidden, permissions are OK

    - by Mario De Schaepmeester
    First of all, I will mention that the permissions are fine for the document root directory, which is /webapps/nimbus/www/public_html The www directory contains a PHP application. PHP is a problem for later if it doesn't work, as I've tested it with a plain html file (does not work either) I just get 403 forbidden responses. The permissions are 755 on webapps and all subdirectories. I've checked other questions here and on the internet, but it was all about those permissions. Whatever info you still need, just ask, I don't know what's relevant as it's the first time ever I'm using webmin or configuring apache.

  • how do I setup Apache's Content-Encoding Header?

    - by Nick
    When attempting to validate my site with the W3C validator, it returns the error, "Don't know how to decode Content-Encoding 'none'". Firebug confirms that my server is sending the header, "Content-Encoding: none". But I can't find any directive in apache2.conf or in my vhost that sets the Content-Encoding header. Where does the directive go, and what should it be set to? UPDATE: On further examination it seems something is wrong with mod_deflate (gzip). It's zipping my css files just fine, but is not zipping the html generated by my php scripts. I have: AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css And the pages are showing a mime type of: "text/html". But content encoding is "none" and they aren't zipping. Perhaps these issues are related?

  • Using nginx and/or varnish to cache server-generated 301 redirects

    - by rlotun
    I'm implementing a sort of url-shortener service. What happens is that I have some backend app server that takes in a request, does some computation and returns a 301 redirected url back upstream to an nginx frontend: request ---> nginx ----> app_server What I want to be able to do is cache this returned 301 url for the same request (a specific url with a "short code"). Does nginx do this caching automatically? Or should I drop in something like varnish in between nginx and the app_server? I can easily cache this in memcache, but that would require hitting the app_server, which I'm sure can be dispensed with after the first request. Thanks.

  • nginx rule to capture header and append value as query string

    - by John Schulze
    I have an interesting problem I need to solve in nginx: one of the sites I'm building receives inbound traffic on port 80 (and only port 80) which may have a certain header set in the request. If this header is present I need to capture the value of it and append that as a querystring parameter before doing a temporary redirect (rewrite) to a different (secure) server, while passing the paramater and any other querystring params along. This should be very doable, but how!? Many thanks, JS

  • Enforcing a specific order for cookie headers

    - by Paul
    We have an application that cares about the order of cookie headers. It shouldn't, since this isn't mandated by the standards and indeed we're getting the headers in various different orders So we would like to rewrite the headers in Apache so that the cookie headers always appear in a specific order. Is there any way of doing this? An ideal solution would be specifically about cookie headers, but something that lets us mess with the header order more generally would do too.

  • Circumventing a manual HTML login page for "unclassified" websites

    - by auramo
    The IT department just made my life a little bit harder again: they introduced a manual HTML login page for all websites they have not "classified". This means that all the applications which try to access unclassified websites for e.g. downloading plugins do not work. Examples: Eclipse plugin installation, Maven builds etc. What would be the easiest workaround for this? The best I've come up with is try to extend/customize Ruby's httpproxy.rb that comes with Webrick. I would automate the manual login process whenever that login response page is detected. This sounds quite painful, and I think there might/should be simpler options?

  • How to set up custom 401 error page or redirect in WSS3 SP2

    - by Stacy Vicknair
    I've got a WSS3 sharepoint site that requires windows authentication both in IIS and via the Sharepoint site. What I would like to do is in the case that a user does not provide valid AD credentials they are redirected to a custom error page. Currently, if the user immediately hits cancel when prompthey will see a plain text response of "401 UNAUTHORIZED". If they make an attempt and then hit cancel they instead see a blank page. I have looked into several options such as customErrors, httpModule interception (only saw examples for this after the user is authenticated), IIS Url rewrites (didn't see how this could help). Is there a good way to do this?

  • Broadband Traffic Question

    - by rutherford
    I have a broadband ADSL line with plus.net in the UK. Having checked the modem there is no firewall or any weird features enabled. But since I arrived at the apartment (the broadband already being installed), I cannot log into Twitter nor update any of my wordpress blogs (I can browse them and log in, but cannot save any edits or new posts). It only seems to affect these two sites in their unique ways. If I take the netbook I use in this place out to say a McDonalds or some other wifi access point then these sites work fine again. Anyone know what could possibly be preventing access of the pages in question? The only thing common to these pages are the POST response they are expecting. But POST form submission works fine on other sites...

  • Winamp "Now Playing" POST to PHP script

    - by Brad
    I have tried/researched 8 or so different plugins for Winamp that allow this functionality, and none of them seem to work on Windows 7 x64! I need a plugin for Winamp that will send the current playing track information to a PHP script, via GET or POST. I have almost no requirements... it can be the name/artist, or the filename (preferred). No fancy functionality needed, just something basic! The four that I actually are: Now Playing XML HTML Server SongStat Currently Hearing Any suggestions? (Note to Moderators: No, I'm not looking for "shopping recommendations", I just need a plugin that works. There probably is only "one answer" to this question, and if there isn't, feel free to make it a CW.)

  • Only allow the POST method for a specific file in a directory

    - by Dave Chen
    I have one file that should only be accessible via the POST method. /var/www/folder/index.php The document root is /var/www/ and index.php is nested inside a folder. My configurations are as follows: <Directory "/var/www/folder"> <Files "index.php"> order deny,allow Allow from all <LimitExcept POST> Deny from all </LimitExcept> </Files> </Directory> I visit my server at 127.0.0.1/folder but I can GET and POST the file just like normal. I've also tried reversing the order, order allow,deny, require, limitexcept and limit. How can I only allow POST requests to be processed by one file in a folder?

  • Cache Control Headers with IIS 7.5

    - by Brad
    I'm trying to wrap my head around client side (web browser) caching and how it works in relation to IIS 7.5 cache control headers. In particular: If we want to force clients to reload cached resources, how must IIS be configured? Do we need to set expire web content immediately if the resources on the server have a more recent Modified Date (or ETag value)? Right now we're not setting any cache headers. So if I set a cache header of no-cache (which I think is the equivalent of expire web content immediately) will that force the web browser to obtain a new version of a particular file. Or will the browser only request a new version after it deems its current copy to be stale and then from that point forward not cache it? Would a best practice be to set a cache control flag of 1 week, then 8 days before I know I am going to make a change set the cache control down to for instance 30 minutes? But if I do that and then need to immediately expire an item from users caches because there was an issue with it how do I do that?

  • Processing files from a Content Distribution Network problem

    - by Derek
    From what I understand that CDNs are meant to physically cache your static files in multiple regions closer to your users. However, I've noticed a few websites that when a page is requested from their server, they grab the asset files from their cdn, process them (compress, minify, etc.) cache the results on their server and then send them to the user requesting the page. This doesn't make too much sense to me. Wouldn't processing the files on your server eliminate the gains from using a cdn? Is this a normal way of doing things, or am I not understanding the whole asset management concept?

  • Is it possible to do a 301 redirect AND redirect to the requested resource?

    - by Pure.Krome
    For one of our projects, we're doing a rebranding of the website name, logo, etc... As such, we need to 301 Moved Permenantly redirect all users from the old domain to the new domain. With IIS7, that's pretty simple. We just create a new website that redirects all traffic to a host-headered domain .. to the new one. But this loses their original destination resource. eg. Old Domain: www.OldDomain.com New Domain: www.NewDomain.com User: www.OldDomain.com/user/PureKrome -> 301 --> www.newDomain.com Notice how it's going to the new domain BUT not to /user/PureKrome? How can I do this so it goes to the new domain and keeps the original resource request? I'm guessing URL-ReWriter for IIS7 might help? Also, what happens if I want to do this... CurrentDomain 1: Domain.com CorrectDomain 1: www.Domain.com CurrentDomain 2: AnotherDomain.com CorrectDomain 2: www.AnotherDomain.com Is it also possible to have those in the same IIS website? So any URL to domain.com will 301 to www.domain.com Right now I'm making 2 IIS websites, with a 301 hardcoded (which still means I lose the original resource request, too). Help!

  • google webmaster soft 404 on 301

    - by Daniel
    I'm looking through google webmaster that my page is generating soft 404 errors (https://support.google.com/webmasters/answer/181708?hl=en) google says: We recommend that you always return a 404 (Not found) or a 410 (Gone) response code in response to a request for a non-existing page But I've got redirects set up that handle old pages to redirect to the proper new pages using a 301. The website links changed because of a use of a framework, which allows it to be more consistent, but the old pages till have links out there to these. Should I be worried about this? IS google penalizing the site for this? (Using IIS 8, Tomcat, CF10, Win)

  • How would I recognize the "spoon-feeding problem" on a dynamic webapp server?

    - by Don Spaulding
    The "spoon-feeding problem", as it was recently explained to me, happens when connections to your application server are tied up feeding data across slow network connections to your clients. This makes sense to me and now I understand the importance of putting a highly-concurrent proxy in front of my app servers. My question is, how did the first person to recognize this problem figure it out? What *nix tools and troubleshooting techniques would help me to recognize this problem if I hadn't had it explained to me?

  • MySQL based authentication with crypt()ed password fails in Apache 2.2

    - by Fester Bestertester
    I'm trying to set up a simple CalDAV/CardDAV server with a Radicale backend and an Apache 2.2 frontend. So far, it's all nice and simple, but I can't get the MySQL based authentication to work. I'd like to authenticate users against an existing MySQL database, and I need the REMOTE_USER variable to be set (pretty much like in the configuration examples for Radicale). I've tried mod_auth_mysql, which authenticated the users nicely, but failed to set the REMOTE_USER variable. The newer alternative seems to be mod_authn_dbd, which doesn't seem to like the crypted passwords in the MySQL database. According to the documentation, crypted passwords should work, so maybe I'm just missing a simple parameter. The configuration looks like this: DBDriver mysql DBDParams "sock=/var/run/mysqld/mysqld.sock dbname=myAuthDB user=myAuthUser pass=myAuthPW <Directory /> AllowOverride None Order allow,deny allow from all AuthName 'CalDav' AuthType Basic AuthBasicProvider dbd require valid-user AuthDBDUserPWQuery "SELECT crypt FROM myAuthTable WHERE id=%s" </Directory> I've tested the query, it works fine. And as mentioned before, mod_auth_mysql worked nicely against the same database, but didn't set the required variables. Am I just missing some configuration parameter? Or is mod_authn_dbd just not the right tool to achieve what I want?

  • How to filter Varnish logs based on XID?

    - by Martijn Heemels
    I'm running into infrequent 503 errors which appear hard to pinpoint. Varnishlog is driving me mad, since I can't seem to get the information I want out of it. I'd like to see both the client- and backend-communications as seen by Varnish. I thought the XID number, which is logged on Varnish's default error page, would allow me to filter the exact request out of the logging buffer. However, no combination of varnishlog parameters gives me the output I need. The following only shows the client-side communication: varnishlog -d -c -m ReqStart:1427305652 while this only shows the resulting backend communication: varnishlog -d -b -m TxHeader:1427305652 Is there a one-liner to show the entire request?

  • What does this error mean in my IIS7 Failed Request Tracing report?

    - by Pure.Krome
    when I attempt to goto any page in my web application (i'm migrating the code from an asp.net web site to web application, and now testing it) .. i keep getting some not authenticated error(s) . So, i've turned on FREB and this is what it says... I'm not sure what that means? Secondly, i've also made sure that my site (or at least the default document which has been setup to be default.aspx) has anonymous on and the rest off. Proof: - C:\Windows\System32\inetsrv>appcmd list config "My Web App/default.aspx" -section:anonymousAuthentication <system.webServer> <security> <authentication> <anonymousAuthentication enabled="true" userName="IUSR" /> </authentication> </security> </system.webServer> C:\Windows\System32\inetsrv>appcmd list config "My Web App" -section:anonymousAuthentication <system.webServer> <security> <authentication> <anonymousAuthentication enabled="true" userName="IUSR" /> </authentication> </security> </system.webServer> Can someone please help?

  • Amazon S3 not sending Content-Type header

    - by Luke____
    I have an application that downloads content from various sources. It relies on the "Content-Type" header being set on images. The majority of web-servers do this correctly but it appears Amazon S3 server is not setting the Content-Type. I assume Amazon servers are configured correctly so what could be the problem? Are these images not uploaded correctly? Or should I not be relying on content type being set? Example Thanks

  • IPTables configuration help

    - by Sam
    I'm after some help with setting up IPTables. Mostly the configuration is working, but regardless of what I try I cannot allow localhost to access the local Apache only (i.e. localhost to access localhost:80 only). Here is my script: !/bin/bash Allow root to access external web and ftp iptables -t filter -A OUTPUT -p tcp --dport 21 --match owner --uid-owner 0 -j ACCEPT iptables -t filter -A OUTPUT -p tcp --dport 80 --match owner --uid-owner 0 -j ACCEPT Allow DNS queries iptables -A OUTPUT -p udp --dport 53 -j ACCEPT iptables -A OUTPUT -p tcp --dport 53 -j ACCEPT Allow in and outbound SSH to/from any server iptables -A INPUT -p tcp -s 0/0 --dport 22 -j ACCEPT iptables -A OUTPUT -p tcp -d 0/0 --sport 22 -j ACCEPT Accept ICMP requests iptables -A INPUT -p icmp -s 0/0 -j ACCEPT iptables -A OUTPUT -p icmp -d 0/0 -j ACCEPT Accept connections from any local machines but disallow localhost access to networked machines iptables -A INPUT -s 10.0.1.0/24 -j ACCEPT iptables -A OUTPUT -d 10.0.1.0/24 -j DROP Drop ALL other traffic iptables -A OUTPUT -p tcp -d 0/0 -j DROP iptables -A OUTPUT -p udp -d 0/0 -j DROP Now I have tried many permutations and I'm obviously missing everything. I place them above the in/out bound SSH to/from, so it's not the precedence order. If someone could give me the heads up on allowing only the local machine to access the local web server, that'd be great. Cheers guys.

  • How do I configure Jetty (via jettyrunner) so that it names a character set in the Content-Type response header?

    - by Pointy
    I use Jetty (via the oh-so-handy Jetty Runner) for day-to-day web application testing. One thing I've recently stumbled on is the fact that I don't get a character set called out in the "Content-Type" response header all the time. I do get it in response to my application's XMLHttpRequest transactions, but not for plain old pages loaded by <a> links or whatever. I've read a little bit about how to set up a Jetty config file, but I've never been able to completely understand that; all servlet containers are complicated, and while Jetty is pretty simple it's just weird enough that I don't grok the overall idea. Thus, all I do to launch my app is to run the Jetty Runner .jar file with a couple of simple arguments to set up the port number and logfile path, and then I just give it the .war file to run. It works great — except for the missing character set :-) Anybody have a quick sample config file that might fix this? edit — oh if it matters, I'm running Jetty 7.0.0 RC3; I've also tried with a slightly newer version (still 7.something) with exactly the same issue. All my testing is on Ubuntu.
