BIG-IP irule : determine page-type
F5 BIG-IP Virtual Edition v11.4.1 (Build 635.0) LTM on ESXi Request urls can be in following forms : www.gofish.com www.gofish.com/barracuda www.gofish.com/sharks/blacknose www.gofish.com/species.html www.gofish.com/bait.aspx www.gofish.com/bait.aspx?color=green I need to determine if a request is for a page ( *.html , *.aspx ) vs a resource ( barracuda , /sharks/blacknose ). More specifically, I need to determine if request is for an .aspx page.
How to change the default max length of Query string in URL
My company is currently using BigIP v13.1.3.4 without ASM in place. RFC 2616(Hypertext Transfer Protocol — HTTP/1.1) states there is no limit to the length of a query string (section 3.2.1).RFC 3986(Uniform Resource Identifier — URI) also states there is no limit, but BigIP has limited the query string to magical max value, 1354. Any query string exceeding 1354 won't work. Can F5 BigIP experts tell me where I can change that default value for max length of query string? This limitation did cause trouble for situation where BigIP works SAML 2 Identity Provider, and the counterpart Service Provider sends AuthnRequest by REDIRECT binding method. one example of such a problematic long query string: myqueryparam=nVfJkqNIEr3rK9LUR1kVmxaQVZZZBDsCBEhCgssY%2ByI2sUtfPyizKiurZ6atpw%2BYFIHHC%2FfnzyOcb42TZ9UWdG1cGMGtC5r2Zcyzotm%2BvXidd3WxLZ0mabaFkwfNtvW2B6DIW%2Fwruq3qsi29Mpu%2FgKYJ6jYpC7osmi4P6kNQ94kXnAz5dR63bdVsESQoxr5q2mmLr9Pv16LcLpcE8twHaSpkAguTLECqsmkRx2vmL8xkmRTOE%2FYXiB%2F0P1a%2Fr0z8X0vrwE%2FqwGvL%2Bg2kacr5i8i8zv%2BFUR5FOit%2F7bnuyglxFN0QobP0KIrASTJcL9dL3yEm46bpArFoWqdoX%2Bc4imNf0OUXHD9iqy1BbonVVxTF7fkLV9Ze8MbZ6zx0siaYv2g%2FuIBJ4SdF9NfEue9GzVY4HrUv2v5wnL%2BYQd28RToZzL9%2Fewa3ffOn%2FpSQv4Z1fmZh%2Fv0vOf%2BGfEL%2F%2Fs1vtockmoju6uDHXn7zzviEMAzD14H4WtYRMvGGIiiFTDZ%2Bk0R%2FzD%2FWBr5YhOU%2FWEw7RVkknpMlj7dEK0Ebl%2F4LyKKyTto4%2Fx9IGIKhT6Qvweh98bBl8ccc%2BT2Qvwn0m0t143xpYgf7gWUEYVAHhRe8nAzxdf7H35XR2%2BJj7RRNWNZ58%2Fvw%2F%2FMoKPogK6vA%2F9L8DOyHc38f8L9w9f1b4G3Fwsu6JukD9SmkyvGC5kcCA%2B%2FvQ03CD8JklJNmqpixeXqHfHbvT8N3NpgkmhT5T1L0KT3vIKaTdcH3IrmKFmtf43EfRLWrF5bSWykmyJT3%2BubAZ%2BO3iY%2Fkvg9%2Fifh3Gb2vOHi7Cz56NSVSxI00ghWxUcAdtbANqxb12e3jNlDlVsOvuLyPz9YFMPI5rHYyt0%2BXqzwZlLsgeaV5laNTsRiDNPAUOkdsZyWVTLy8ohAC5WawSHmMJTIdWiUN1oK8kGS3uFQ5H3JS%2BLiqVEEgvaDaqwYYdrokKXNPsisx1c6Q4SsbVbB9wpMno8VrXyROZhepY6WuF3RSubI5EOy5Ol30sLwnmr4z6DErKuNy7X2pOYchqnq9IOIq1gk8BlG9u2Or6B6nl0RiRWa5TJgjMHilp7gF6xIadylJTIDrMjtiSzOOr7GjcrQSOWVV8o29Njt7gWQerKNIwfRVqO5O3OiMu2zU03ZBDvfl8Pr6Qf0nrp%2F074L7RyouK5RinNb5GNDPMy6czow2%2BK6IIjcyNA139wgMIgSRErKuNy7X2pOYchqnq9Iafdasdafdasdad
iRule to Forward Traffic Based on URL Name
Hi, I am in a situation where we have shortage of IP address and am looking for an alternative way to forward traffic to pools based on URL. I am not really good with iRule hence looking for assistance and I have seen posts based on URI, but i am looking for assistance with URL. Eg: 1 VIP and based on the url name, the traffic needs to be forwarded to Pool. Help on this is appreciated
Redirect and hide URL+URI
Hi, Trying to set up a VMware Horizon admin connection to rewrite and hide the underlying URL and for the life of me I can't figure it out although it feels like I should be able to. Requirements: redirect --> http://myURL.domain.com/ OR https://myURL.domain.com/ to --> https://mySERVER.domain.com/myURI/#/login mask --> https://mySERVER.domain.com/ANYURI as --> https://myURL.domain.com/ANYURI The idea being that whenever a user navigates to the URL, all they ever see is the URL and corresponding URIs after the trailing "/" in the browser. Just seeing the base URL and no URIs after the trailing "/" is also ok. I have successfully done the redirection on the VS with both iRule and Policy but the masking is giving me a headache. Searching and finding various solutions that did not seem to address this particular type of request made my headache worse. I have about 8 months of experience with load balancers (maybe 4 months with F5 BIG-IP LTM specifically). Thanks.irule to redirect based on HTTP header
Hi guys, I am not a professional coder and Im trying to find and start to develop a irule to redirect our HTTP request to a especific pool, but cant find nothing similar to start a new one. Our LTM receives from the browser an HTTP header with this information: VALIDADOR_USER: 10\r\n (I take it just equals from the wireshark, the number is random 10-27) I want to try a code that will take it number from VALIDADOR_USER and load balance to 4 diffent pools. i.e.: if VALIDADOR_USER: 10 or 11 or 12 or 15 > pool_1 if VALIDADOR_USER: 16 or 17 or 18 or 19 > pool_2 if VALIDADOR_USER: 20 or 21 or 22 or 23 > pool_3 if VALIDADOR_USER: 24 or 25 or 26 or 27 > pool_4 I wonder if its possible to do something based on comparing this values through datagroups and if it matches the LB will be trigged.. Please, can you guys give me a help ? Regards, Cadu.
URL Category Database Useless
I have been struggling with the extremely worthless WebSense URL Category database. I say this because categories like "Information Technology" have several sub-categories within it. The problem with categories like these comes with creating and implementing Filters. It appears that with a filter you must allow ALL sub-categories in order for the main Category to be allowed. This is a problem with say.....Business & Economy, because the two sub-categories are "Hosted Business Applications" and "Financial Data & Services". So in order to get the main category of "Business & Economy" to be allowed (because Websense DOES categorize sites into the main categories) via a filter, I must allow BOTH "Hosted Business Applications" and "Financial Data & Services". This is a problem, because "Hosted Business Applications" is arguably NOT really "Business & Economy", but more appropriately falls under "Information Technology". The concept of having sub-categories is great, but that means your Main Categories become useless, if you aren't allowing ALL sub-categories, and if that is how it truly does work with filtering, then it sort of NEGATES having sub-categories. It may have been better to either make everything its own category, or just simply stick with the 40+ main categories only. On a side note, it appears as though many of the major Social Media platforms have got their own main category, but again if WebSense categorizes anything from Facebook, Twitter, etc. as "Social Web - Facebook" or "Social Web - Twitter", and you aren't allowing ALL of the sub-categories wihtin those respective main categories, it will get blocked. Am I way off base on this assessment of how all this works; am I missing something? Has anyone else run into these same issues?
iRule to certain url
Hi, i am not really that familiar with iRules, so please help me. So this is my setup: VIP: 1.1.1.1:443 Pool: 2.2.2.2:2001 How can we set an irule that if the user access https://1.1.1.1/Administration/services/ it will redirect it to the pool http://2.2.2.2:2001/Administration/services/ ? If number 1 is possible, how can we hide the real ip of the pool? i mean the user must not see it's 2.2.2.2, it should be still 1.1.1.1 ? Thanks, hoping for feedbacks.
