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:
