I use request.remote_addr to get the users IP address. That worked great when I was running only one server. Now I have three with a load balancer. The IP address that is returned now is that of the server the user is pointed to by the load balancer. Question is: How can I get the users IP address now that I am using load balancers?

The Alpha Software Forum is a free forum created for Alpha Software Developer Community to ask for help, exchange ideas, and share solutions. Alpha Software strives to create an environment where all members of the community can feel safe to participate. In order to ensure the Alpha Software Forum is a place where all feel welcome, forum participants are expected to behave as follows:
Be sure all comments and threads you post are respectful. Posts that contain any of the following content will be considered a violation of your agreement as a member of the Alpha Software Forum Community and will be moderated:
If a thread or post is found to contain any of the content outlined above, a moderator may choose to take one of the following actions:
Moderators may also rename posts and threads if they are too generic or do not property reflect the content.
Moderators may move threads if they have been posted in the incorrect forum.
Threads/Posts questioning specific moderator decisions or actions (such as "why was a user banned?") are not allowed and will be removed.
The owners of Alpha Software Corporation (Forum Owner) reserve the right to remove, edit, move, or close any thread for any reason; or ban any forum member without notice, reason, or explanation.
Community members are encouraged to click the "Report Post" icon in the lower left of a given post if they feel the post is in violation of the rules. This will alert the Moderators to take a look.

Bonus TIPS for Successful Posting
Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.
When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.
The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.
When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.
A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.
If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.
When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.
Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.
- Be professional in your conduct
- Be kind to others
- Be constructive when giving feedback
- Be open to new ideas and suggestions
- Stay on topic
Be sure all comments and threads you post are respectful. Posts that contain any of the following content will be considered a violation of your agreement as a member of the Alpha Software Forum Community and will be moderated:
- Spam.

- Personal attacks, insults, or subtle put-downs.
- Harassment, bullying, threatening, mocking, shaming, or deriding anyone.
- Sexist, racist, homophobic, transphobic, ableist, or otherwise discriminatory jokes and language.
- Sexually explicit or violent material, links, or language.
- Pirated, hacked, or copyright-infringing material.
- Encouraging of others to engage in the above behaviors.
If a thread or post is found to contain any of the content outlined above, a moderator may choose to take one of the following actions:
- Remove the Post or Thread - the content is removed from the forum.
- Place the User in Moderation - all posts and new threads must be approved by a moderator before they are posted.
- Temporarily Ban the User - user is banned from forum for a period of time.
- Permanently Ban the User - user is permanently banned from the forum.

Re: Tracking user IP through a load balancer
Hi Mike - just wondering - what load balancer are you using and how do you find its performance? - and hi Steve.

Re: Tracking user IP through a load balancer
As Frank mentioned, the issue is that the user does not connect to the server directly. Instead it connects to the load balancer, and then the load balancer connects to the server. This means that all the server knows is that a connection was initiated from the load balancer.
Talk to RackSpace about their load balancer options. Some have the ability to spoof the source IP address so it looks like the real client to the server. Others can set an optional header with the actual source IP address and you can read that value from Xbasic. X-Forwarded-For is a header used by many balancers and proxies to make the original source address available. You could easily read this header from your code.Last edited by Lenny Forziati; 04-03-2014, 11:15 AM.
