Introduction
RFC 2616 (Hypertext Transfer Protocol: HTTP/1.1) states that there is no limit to the length of a query string (section 3.2.1). RFC 3986 (Uniform Resource Identifier – URI) also states that there is no limit, but states that the hostname is limited to 255 characters due to DNS limitations (section 2.3.3).
Ok Although there is officially no limit specified by RFC 2616, many protocols and security recommendations state that maxQueryStrings on a server should be set to a maximum character limit of 1024. While the entire URL including the query string, should be set to a maximum of 2048 characters.
Based on research found in Boutell. com: Microsoft Internet Explorer (browser) Microsoft states that the maximum length of a URL in Internet Explorer is 2083 characters, with a maximum of 2048 characters in the path portion of the URL. Attempts to use longer URLs generated a clear error message in Internet Explorer.
Please check the configuration/system.webServer/security/requestFiltering/requestLimits@maxQueryString setting in applicationhost.config or web.config. I did this by following the documentation and changing the max query string length from 2048 to 4096 characters.
What is the maximum length of a query string in http?
While the full URL including the query string should be set to a maximum of 2048 characters. This helps prevent the DDOS vulnerability of slow HTTP requests on a web server. This is commonly listed as a vulnerability in Qualys Web Application Scanner and other security scanners.
Although there is no official limit specified by RFC 2616, many protocols and security recommendations state that maxQueryStrings on a server should be set to a maximum character limit of 1024 While the full URL including the query string should be set to a maximum of 2048 characters.
I did this, following the documentation and modifying the maximum length of the query string from 2048 to 4096 characters. The change above obviously took effect, as the original error message disappeared.
7 replies. As already mentioned, HTTP itself imposes no hard-coded limit on the length of the request; but browsers have limits ranging from 2kb to 8kb (255 bytes if you count very old browsers).
What is the maximum character limit for a query string?
Although there is no official limit specified by many security protocols and recommendations, it does state that the maximum number of QueryStrings on the server should be set to a maximum character limit of 1024.

The Apache’s official documentation only mentions a single 8192 byte limit on a single field in a request. Microsoft Internet Information Server (Server) The default limit is 16384 characters (yes, the Microsoft web server accepts longer URLs than the Microsoft web browser). This is configurable.
RFC 3986 also states that there is no limit, but states that the hostname is limited to 255 characters due to DNS limitations (section 2.3.3). Although the specifications do not specify a maximum length, practical limits are imposed by web browser and server software.
What is the maximum length of a URL?
The maximum length of a Web page URL in Microsoft Internet Explorer is 2083 characters. But, if you implement the GET method, you can limit it to a maximum of 2048 characters. It is minus the number of characters in the actual web page path. 6.

What is the maximum length of a URL query string?
While the full URL including the query string should be set to a maximum of 2048 characters. This helps prevent the DDOS vulnerability of slow HTTP requests on a web server. This usually appears as a vulnerability in Qualys Web Application Scanner and other security scanners.

How long can a query string be in SQL Server?
Is there a limit to the SQL query length (in terms of characters or tokens or whatever) in SQL Server? View activity on this post. I never ran into the problem that the SQL query was too long in terms of the number of characters, but there is a maximum number of tables a query can reference (256) and I ran into this limitation several times.
RFC 2616 (Hypertext Transfer Protocol HTTP/1.1) states that there is no limit to the length of a query string (section 3.2.1).

A variable length string. Note: Trailing spaces are stripped when the value is stored (this differs from the ANSI SQL specification). The length range is from 1 to 255 characters. VARCHAR values are sorted and compared case insensitive unless the BINARY keyword is provided.
Does this length depend on the version of SQL Server? @SQLStatement can contain X characters. What is X? View activity on this post. This will be 65,536 times your network packet size, according to the Show Activity documentation for this article.
What is the maximum length of an HTTP request?
think the default is 2 megabytes. The documentation states that this value can be configured up to the limit of 32-bit signed integers in bytes, although other configuration options may also need to be changed to reach this limit. What is the maximum length of an HTTP GET request? gives a pretty good synopsis.
Uncompressed request and response headers. The size of today’s request headers ranges from around 200 bytes to over 2 KB. As applications use more cookies and user agents extend functionality, request header sizes Typical headers of 700 to 800 bytes are common. The HTTP HEAD response from www.google.com is 823 bytes as checked a moment ago. It is without any authentication.
There is no defined length other than the maximum length of a URL, which is 2 KB or less. However, there are a number of parameters that define and influence it, the web server and the code interpreter. For large POSTs, the limits can be mitigated by segmentation. The HTTP protocol does not specify a limit.
In HTTP you always have to give a content length to the other side (this is for both request and response), if your response is really big it’s up to the client to treat it in an acceptable way (for example, passing it directly to a server.records).

Example 1 : Input: str=takeuforward Output: a Explanation: The character ‘a’ and ‘r’ have the same maximum occurrence i.e. 2. Therefore we can print either Example 2: Input: str=apple Output: p Explanation: The character ‘p’ has the maximum occurrence, i.e. 2. Disclaimer: Don’t jump to the solution, try -la yourself first.
Given a string S of size N and Q queries Each query consists of L and R ( 0 <= L <= R < N ) The task is to print the character that appears most often in the given range.If there are multiple characters that appear the maximum number of times, write the least lexicographically.
What is the maximum number of characters in an Apache URL?
Apache’s default URL length of 8177 characters is sufficient for most websites. However, if your requests exceed this limit, Apache will throw a Request URI too large error. but browsers have limits ranging from 2048 characters allowed in GET method.

Conclusion
What is the maximum length of the domain name? The maximum number of characters you can have in a website address to the left of the . has 63 characters. This is an awfully long URL and we do not recommend choosing such a long domain under any circumstances.

The maximum number of characters you can have in a website address to the left of the . has 63 characters. It’s an awfully long URL and we don’t recommend choosing such a long domain in any way. For more advice on choosing names, check out our guide to choosing domain names or start your domain name search.
So, using only one character per tag, the limit is 127 levels: 127 characters plus 126 dots has a total length of 253. In practice, some domain registrars may have shorter limits.
